IBC CX 150 User Manual

1. Disconnect and cap off the 120VAC leads connected to PV-L/PV-N
2. Provide 24VAC for the zone valves to the PVPower contacts on the Pump/ Zone Valve
terminal block

3.14.6 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.
