SETTINGS HERE
Programming and setting up the BMPlus
3000 to control your HVAC system is very easy!
Look below for an explanation of each dip
switch function and choose your settings.
Some functions may not apply to your application.
Then use a pencil to mark/record your settings. If the
settings get changed later on, you will
have a record of the original settings.
HP < SYSTEM > GAS
Choose the type of HVAC system you want to control. Select
if your system is a standard Gas or Oil furnace. Also applies to straight electric furnaces or hydronic (hot water coil)
heating systems. NOTE: If HP is selected at dip switch 1, Y2 is not available. Y2 is only available in GAS mode.
DF < HP > CONV
Choose the type of Heat Pump you want to control. Select
furnace backup heat. Select
Also applies to Ground source/Geothermal heat pumps.
HC < TSTATS > HP
Select HC, if you want to use regular Heat/Cool thermostats on your job. Select HP, if you want to use Heat Pump
thermostats on your job. Remember that you can use standard HC T-stats on a Heat Pump application.
IMPORTANT NOTE: The BMPlus 3000 Zone Control System allows Heat Pump thermostats to be connected to all zones.
When doing so, make sure you turn the 2nd stage timer to the "OFF" position. Using heat pump thermostats means that the
zone panel will obey thermostatic demands and ignore Timer operations. This comfort over-ride feature provides a level of
versatility to your zoning system and gives the homeowner comfort control over the system, instead of waiting for the
adjustable timer to energize 2nd stage heat.
O < RV > B
Select the correct Reversing Valve signal for your particular Heat Pump. Choose "O" for any heat pump that energizes
the RV in the cooling mode. Choose "B" for any heat pump that energizes the RV in heating mode.
OAS < 2nd STAGE > TIMER
OAS
Select , if you want to delay 2nd stage heat based on the outside air temperature sensor. Select
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
OFF
Select , if you do not want to inhibit 2nd stage heat/cool based on the total number of zones calling. Select
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. If DF or OAS has been selected, the 50% rule will apply to
cooling operations only. 2nd stage heat will not be affected. The 50% rule will always dominate the 2nd stage timer or
thermostat demands unless Emergency mode is active.
OFF < SAS > ON
OFF
Select , if you do not want to use the supply air sensor included with the BMPlus Zone Control system. Select
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
GAS
Select , if your HVAC system is a gas or oil forced air furnace. Select
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
mode is automatically set for you. There is no need to move this switch when setting up for Heat Pump operations.
