insTallinG The Trm reCeivinG module
TRM stands for Transmitting and Receiving Module. The
TRM communicates with the TSTBT4H2CP Thermostat
Series using the MODBUS protocol and then translates
the MODBUS protocol to pulses and relays these signals
to the HVAC equipment.
The Receiving Module can be installed adjcent to or
within the HVAC equipment.

There are two LED lights on the TRM. One is the COM
light which blinks green when communication is
happening between the TRM and the thermostat. This
light will normally blink about every 10 seconds as the
thermostat and TRM are in constant communication for
status updates. If communication is lost for more than 10
minutes, the COM LED will become red. A certifi ed
licensed technician should be called to service the system
if this occurs.
The other LED is labeled HVAC. This light indicates if the unit
is actively heating or cooling. If the unit is cooling, then the
LED is yellow, if the unit is in heating, then the LED is red. If
the thermostat is satisfi ed, then the LED if off.
