Communicating
Thermostat
NOTE 1:
Humidify control (IAQ relay) can be
digitally triggered via each Communicating
Thermostat. The thermostat demanding humidity
must be calling for FAN as well.
See Page 8.
NOTE 2:
There is no need to connect an OAS sensor
directly to the UT3000. The communicating outdoor unit
provides the outside air temperature value to the UT3000,
and the UT3000 shares that same outside temperature
value with all communicating thermostats. If the network is
unstable or the outdoor unit is non-communicating, the
UT3000 LED screen will display "OAS BAD". This means
the UT3000 will not be able to share the outside air
temperature with the communicating thermostats.
See Page 7.
