ViewStat Communicating Thermostat
Support Module Specifications
There are two types of support modules available for the ViewStat:
VST-TTM Temperature Module : The VST-TTM support module offers versatility in
climate control. A set of onboard dip switches on the VST-TTM circuit board allow you
to determine whether you want the two remote temperature sensor inputs to control,
monitor or do a combination of both. This temperature data is sent back to the ViewStat
Thermostat, allowing you to accurately control and monitor temperature in a given area
or multiple areas.
VST-TRH Temperature and Humidity Module : The VST-TRH support module brings
further versatility to the HVAC system. A set of onboard dip switches on the VST-TRH
circuit board allow you to determine whether you want the two remote temperature
sensor inputs to control, monitor, or both. The temperature/humidity data is sent back to
the ViewStat, allowing you to accurately control and monitor temperature/humidity in a
given area or multiple areas.
