SL 30-175 MODULATING GAS BOILER

1.8.6 Thermostat Heat Anticipator

IBC “Therm.” contacts draw no power, so an anticipator setting for the thermostat

is not applicable with the SL modulating series boilers. 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.
