Thermostat & Outdoor Curve
– A central heating call from a dry contact switch will enable the appliance and the setpoint will vary with the outdoor tem-
perature for central heating calls.
Thermostat & Setpoint
- A central heating call from a dry contact switch will enable the appliance and the setpoint will be fixed for central heating calls.
Constant & Outd. Curve
- The appliance will maintain setpoint and the central heating circulators will be constantly enabled without an external call from
a dry contact switch. The central heating circulators will be disabled when the outdoor temperature exceeds the Warm Weather Shutdown Temperature
setting. The setpoint will vary with the outdoor temperature for central heating calls.

0 - 10V Power Modulation
- This option allows the appliance firing rate to be controlled by an external control system. Based on the control input volt-
age, the appliance will start to operate for heat demand. The CH temperature is limited by the Absolute maximum temperature.

0 - 10V Temp. Modulation
- This option allows the appliance CH temperature to be
controlled by an external control system. Based on the control input voltage, the
appliance will start to operate for a heat demand.
