Select CH Demand
prompts the installer to select how a CH Demand is generated. There are three Select CH Demand options,
among which the installer must make a selection.
Thermostat & Setpoint
- This option is only displayed when no outdoor temperature sensor is connected. A central heating call from
a thermostat or zone panel will enable the HeatMaster and the setpoint will be fixed for central heating calls. When Thermostat &
Setpoint is selected, the CH1 Setpoint screen appears.
Constant & Setpoint
- The HeatMaster will maintain setpoint without an external CH call from a thermostat or zone panel. The set-
point will be fixed for CH calls. When Constant & Setpoint is selected, the CH1 Setpoint screen appears.
