Explanation

CH Settings

4. Central Heating (CH) modes available:

• CH Mode = 0 ‘CH with Thermostat’

•

Boiler will attempt to satisfy CH demand while CH

thermostat input is closed.

•

Boiler will modulate its firing rate to maintain CH set

point and match system heat load.

• CH set point adjusted in ‘Settings’ submenu under ‘User

Menu’

• CH Mode = 1 ‘CH with Thermostat and Outdoor Reset’

•

Boiler will attempt to satisfy CH demand when CH

thermostat input is closed.

•

Boiler will modulate its firing rate to maintain CH set

point and match system heat load.

• CH set point calculated as function of outdoor

temperature using outdoor reset curve. See figure A-2

• CH Mode = 2 ‘CH with Full Outdoor Reset’

• CH demand is determined by outdoor temperature and

Warm Weather Shutdown temperature.

•

Boiler will permanently attempt to satisfy CH

demand, when CH demand is available.

• CH thermostat input is ignored.
• CH set point calculated as function of outdoor

temperature using outdoor reset curve. See figure A-2

• CH Mode = 3 ‘CH with Permanent Demand’

• CH demand is permanently on.
•

Boiler will permanently attempt to satisfy CH

demand.

• CH thermostat input is ignored.
• CH set point is adjusted in ‘Settings’ submenu under

‘User Menu’

Note:

• Once CH demand is satisfied (i.e. CH thermostat opens or

boiler determines its minimum firing rate exceeds system

heating load):

•

Burner shuts off, boiler enters post purge.

• CH pump continues to run for 30 seconds.
•

Control will wait until Anti-cycle time of 180 seconds

elapses before boiler fires again. Prevents short-

cycling.

• The internal heat exchanger pump is energized anytime demand

exists regardless of Pump Mode setting or type of demand (CH or

DHW).
