3.13.5 Thermostat / sensor wiring
Each of the four loads has dry contacts for thermostats as marked on the lower connector strip
(e.g., "Therm 1"). Gang lines from a multiple-zoned load (e.g., off the end-switches for each
radiant floor zone) present a common thermostat signal to the controller. Ensure that there are no
disturbing influences on the call-for-heat lines - for example, that there are no coils to switch an air
handler motor. Most power stealing thermostats can be connected directly to the Therm
terminals. Consult the Controller manual for more detailed instructions.
3.13.6 Thermostat heat anticipator
IBC “Therm” contacts draw no power, so an anticipator setting for the thermostat is not applicable
with these appliances. In the case of a single temperature / heat load where zone valves are used
to manage individual thermostatically controlled zones, each room thermostat’s heat anticipator
should be adjusted to the current draw of its associated zone valve.
