The thermostat is powered through the wires connecting it to the AQ2000 Series
hydronic zoning controller. Therefore, the thermostat turns on when the controller is
powered. The thermostat can be placed in one of the 3 following modes of operation:
Comfort Mode
The thermostat is normally in the Comfort mode. In this mode, the
temperature is set using the buttons.
Unoccupied Mode
When the Unoccupied mode is activated by the hydronic zoning controller,
the temperature setpoint is lowered by the temperature setback value.
This value is set in the User’s configuration menu (see page 5).
Freeze Protection Mode
When the Freeze Protection mode is activated by the hydronic zoning
controller, the thermostat is placed at the Freeze Protection temperature.
This value is set in the Installer’s configuration menu (see page 10).
