Thermal Circuit Breaker

The BMPlus module has a Thermal circuit breaker that protects the module(s) from shorts in the damper and thermostat field wiring. It will not protect against shorts in the HVAC system wiring.

CAUTION: When the circuit breaker is tripped it will get quite hot. To reset the breaker: Shut off power to the panel. Find and repair the short. Restore the 24VAC power.

Watch Dog Circuit

The processor has a built-in feature that monitors the processor performance and resets the system if an error occurs in operations or due to power failures.

Indoor Fan Control

Any zone can activate the indoor fan and only the dampers in zones calling for continuous fan operation will open. Continuous fan operation will only occur when there are no active or pending, heat or cool demands.

BMPlus 3000 FIRMWARE/HARDWARE FEATURES Indoor Fan Control During Heating

Built-In Timer Settings

A dip switch is provided to enable automatic fan operation in heat mode. Useful for straight electric heat or hydronic heat applications. NOTE: Fan mode is automatically set when Heat Pump is selected. The panel has built-in delay timers that insure safe & reliable operation.

*Opposite Mode Delay Timer *2nd Stage Delay Timer

20 minutes, fixed.

*Supply Air Limit Delay Timer

3 minutes, fixed.

5 to 47 minutes, Adjustable

*Short Cycle Timer

When the system is satisfied, the panel will not resume the same mode for a minimum of 3 minutes.

*Changeover Timer

A built-in timer prevents the system from rapidly switching between heating and cooling modes. At the end of a call, a 4 minute timer is started and the panel will not switch to the opposing mode until the timer has expired.

*Opposite Mode Delay Timer *2nd Stage Timer / OAS 12

33 40

47 5 2nd STAGE Timer / OAS

5 to 47 minutes or 5 to 47 degrees F.

A 20 minute delay must expire, or the active zone(s) must satisfy, before the panel will honor a thermostat demand to changeover to the opposite mode of system operation.

The 2nd STAGE TIMER sets the amount of continuous call time in 1st stage, before second stage heat or cool is energized. NOTE: The potentiometer also serves as the 2nd stage Heat Outside Air Changeover Setting. The BMPlus 3000 can inhibit 2nd stage heat based on Time or Outside Air Temperature. NOTE: An Optional OAS Sensor is required to use the OAS feature. NOTE: 2nd stage cool delay defaults to 15 minutes, if OAS is chosen to inhibit 2nd stage Heat.

HP < SYSTEM > GAS Choose the type of HVAC system you want to control. Select HP, if your system is any type of heat pump. Select GAS, if your system is a standard Gas or Oil furnace. Also applies to straight electric furnaces or hydronic (hot water coil) heating systems.

DF < HP > CONV Choose the type of Heat Pump you want to control. Select DF, if your system is a dual fuel heat pump with gas or oil furnace backup heat. Select CONV, if your system is a conventional heat pump with electric resistance backup heat. Also applies to Ground source/Geothermal heat pumps.

ON < FAN DELAY > OFF Select ON, if you want the indoor blower forced ON at the end of a heat/cool call to assist the zone purge cycle. Selecting OFF will allow the HVAC system to operate the indoor blower, without interference from the BMPlus.

90S < PURGE > 120S Select 90S or 120S, if you want the zone dampers to hold position for 90 seconds or 120 seconds at the end of any heat/cool call. This allows the HVAC system to purge the remaining hot/cold air, into the zone(s) that were calling for it.

OAS < 2nd STAGE > TIMER Select OAS, if you want to delay 2nd stage heat based on the outside air temperature sensor. Select TIMER, if you want to delay 2nd stage heat & cool based on the adjustable on-board timer. NOTE: 2nd stage cool defaults to a 15 minute delay, when OAS is chosen. NOTE: An optional Outside Air Sensor (OAS) is required to use the OAS feature.

OFF < 50%RULE > ON Select OFF, if you do not want to inhibit 2nd stage heat/cool based on the total number of zones calling. Select ON, if you want to inhibit 2nd stage heat/cool based on the total number of zones calling. More than half the total zones must be calling for the same mode, or 2nd stage will not activate. NOTE: If HP has been selected at dip switch 1, Y2 is not available. If DF or OAS has been selected, the 50% rule will apply to cooling operations only. 2nd stage heat will not be affected by this setting. The 50% rule will always dominate the 2nd stage timer unless Emergency mode is active. IMPORTANT NOTE: The BMPlus 3000 Zone Control System allows a 2 stage heating thermostat to be wired to Zone 1 only! Energizing this terminal results in over-ride of any stage 2 heating delay. The BMPlus will remain in 2nd stage mode until that terminal is de-energized. If this occurs in dual fuel mode or emergency mode, the BMPlus will stay in 2nd stage until the heating demand is satisfied. On the next demand for heat, the BMPlus will attempt to activate 1st stage heat unless, Emergency Mode is still active, or the outdoor temperature is low and OAS / DF has been selected. This comfort over-ride feature provides true versatility to your zoning system, and gives the homeowner a level of comfort control over the system.

OFF < SAS > ON

Select OFF, if you do not want to use the supply air sensor included with the BMPlus Zone Control system. Select ON, if you intend to use the included supply air sensor. Refer to the data sheet included with the supply air sensor for details.

GAS < FAN > HYDRONIC Select GAS, if your HVAC system is a gas or oil forced air furnace. Select HYDRONIC, if your HVAC system has a hot water coil, or straight electric heat with no indoor blower support. Useful when you need the indoor blower to run automatically in heat mode, just like it does in cool mode. NOTE: When you select HP on dip switch #1, the indoor fan mode is automatically set for you.

Figure 13 Single stage heat pump and 1or 2 stage furnace. **Note that a Conventional & Dual fuel heat pump wire up more or less the same. The difference is how 2nd stage heat operates. In a Conventional system, the indoor fan & the compressor continues to run when 2nd stage energizes. In a Dual Fuel system, the indoor fan & the compressor shuts down when 2nd stage energizes. The BMPlus 3000 will perform these functions automatically. All you have to do is set the dip switches to the correct settings. Select DF or CONV at dip switch #2. Choose to activate 2nd stage heat by TIMER or by OUTSIDE AIR TEMPERATURE. (Optional Sensor required) You can also use a 2 stage heat thermostat at Zone 1 that will over-ride the delays if the thermostat demands it. When the thermostat 2nd stage heat demand is satisfied, the BMPlus 3000 will stage down, unless DF/OAS has been selected and the outdoor temperature is lower than the OAS changeover setting. In that case the system will continue in FUEL mode, until the heating demand is fully satisfied.

ENHANCED FEATURES AND FUNCTIONS MODULE TO MODULE FACTORY POWER WIRING

SHORTED ZONE FEATURE FIRMWARE

The BMPlus 3000 includes Factory Power Wiring on all expanded systems. The 24 vac power to the expansion modules is fed through the bus cable. This simplifies your wiring and minimizes the chances of reversing polarity.

The BMPlus 3000 Zone Control System includes the Shorted Zone Feature. This feature allows the BMPlus to ignore demands from a zone thermostat that is putting out simultaneous demands for heat & cool. A condition most likely due to a short in the field wiring, incorrect wiring, or a defective thermostat. The BMPlus will honor any legitimate demands from any other zone(s), except the shorted zone. When the problem is identified and repaired, the BMPlus 3000 will automatically recognize that zone.

DUAL FUEL COMPATIBLE

The BMPlus 3000 is compatible with Dual Fuel Heat Pumps. Dual Fuel kits are not required. Select staging based on Adjustable Time Delay or an Optional Outside Air temperature Sensor. The intelligent firmware does the rest. * 5 TO 47 MINUTE 2ND STAGE TIME DELAY SETTINGS

DAMPER WIRING CONTINUED If you need to connect numerous dampers to a single zone, or you are using dampers of unknown current draw, Isolation relays and separate power supplies will be required. Parallel as many dampers as you want as long the total current load of the motor actuators does not exceed the VA rating of the transformer. Other factors should also be considered, such as the full load amp rating of the isolating relay contacts, voltage drops from long wire runs and feeder conductor sizing to junction points. NOTE: Some older style dampers and competitor’s dampers cannot be paralleled and must be isolated or wired in tandem. Contact EWC Controls Technical Support for assistance.

Non-inherently current limiting transformers must have field provided over-current protection on the secondary 24 vac output. The table values provided pertain to genuine ULTRAZONE Dampers and Competitors typical 24 vac Spring loaded dampers. Included in these VA load ratings are the correct number of thermostats, the BMPlus Zone System, and a 5% field factor. Spring loaded dampers draw higher currents & require more power.

T R O U B L E S H O O T I NG SYMPTOM

SOLUTIONS

LED’S are responding properly but HVAC system is malfunctioning.

Check HVAC system wiring for proper connections. Check HVAC system wiring for shorts/miswiring. Check HVAC System. Refer to Technical Bulletin for correct Setup/Wiring/Dip Switch settings.

LED’s are not responding properly and HVAC system is malfunctioning.

Check HVAC system wiring for shorts/miswiring. Check HVAC system wiring for proper connections. Check HVAC thermostat for proper connections. Refer to Technical Bulletin for correct Setup/Wiring/Dip Switch settings.

LED’s illuminate and HVAC system functions normally but dampers do not respond.

Check damper motor wiring for proper connections. Check damper motor 24vac transformer voltage/fuse/BMPluscircuit breaker. Check damper motor wiring for shorts/miswiring. Refer to Technical Bulletin for correct Setup/Wiring. REFER TO THE DAMPER MOTOR TESTING PAGE 8

LED’s do not illuminate and HVAC system does not respond.

Check HVAC/BMPlus system transformer supply voltage. Check HVAC/BMPlus system 24vac transformer voltage/fuse/BMPlus circuit breaker. Check HVAC/BMPlus system wiring for shorts/miswiring.

CHECK YOUR WIRING DETECTING 24vac SHORTS

SYMPTOMS: Module(s) appear to be dead!

HVAC system not responding and BMPLUS 3000 LED’s are off. Dampers not responding and THE BMPLUS 3000 LED’s are off.

If 24vac short has occurred, 24vac will be present at the BMPlus 3000 Module Input terminals R & C; but 24vac will not be present at the Thermostat R&C.

ISOLATING 24vac SHORTS

Disconnect the wire(s) from the ‘R’ terminals on the BMPlus 3000 thermostat terminal blocks , and the “M2/M4/M6’’ terminals on the BMPlus 3000 damper motor terminal blocks. Restore power. If the short is no longer present, Ohm out the thermostat and damper field wiring for shorts/misconnections. Replace or repair wires as necessary. Restore power. Module(s) will resume operation.

F1 circuit breaker protects the BMPlus 3000 and reacts to a short in the damper motor or thermostat component and field wiring.

SOLUTIONS: Remove 24vac power from BMPlus 3000 and allow circuit breaker to cool! Find and repair short(s) in damper and/or thermostat field wiring. Restore 24 vac power.

TESTING THERMOSTATS During a demand for heating, the thermostat should apply a 24vac hot signal to the W and or W2 terminals. During a demand for cooling, the thermostat should apply a 24vac hot signal to the Y and G terminals. During a continuous fan demand, the thermostat should apply a 24vac hot signal to the G terminal. Check to make sure that the thermostat Rc and Rh terminals are connected together, unless your application requires separation of these circuits. Use the (C) Common terminal provided at each thermostat terminal block to wire up full 24 vac hard-wired thermostats. You should reference the (C) Common terminal when troubleshooting incoming thermostat demand signals, even if no wire is connected there.
