INSTALLATION AND OPERATION INSTRUCTIONS
1-28
SL 35-199, SL 45-260 MODULATING GAS BOILERS
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.
