Boiler Demand

To generate a Boiler Demand, a voltage between 24 V (ac) and 230 V (ac) must be

applied across the Boil Dem and the Com Dem terminals (30 and 31).

Caution: The same power supply must be used to power the Boiler Demand, DHW

Demand and the Setpoint Demand circuits since they share the Com Dem terminal.

DHW Demand

To generate a DHW Demand, a voltage between 24 V (ac) and 230 V (ac) must be

applied across the DHW Dem and Com Dem terminals (29 and 31).

Caution: The same power supply must be used to power the Boiler Demand, DHW

Demand and the Setpoint Demand circuits since they share the Com Dem terminal.

Setpoint Demand

To generate a Setpoint Demand, a voltage between 24 V (ac) and 230 V (ac) must be

applied across the Setp Dem and Com Dem terminals (28 and 31).

Caution: The same power supply must be used to power the Boiler Demand, DHW

Demand and the Setpoint Demand circuits since they share the Com Dem terminal.

Mix 1 Demand

To generate a Mix 1 Demand, a voltage between 24 V (ac) and 230 V (ac) must be

applied across the Mix 1 Dem and the Com Dem terminals (25 and 26).

Caution: The same power supply must be used to power the Mix 1 Demand and the

Mix 2 Demand circuits since they both share the Com Dem terminal.

Mix 2 Demand

To generate a Mix 2 Demand, a voltage between 24 V (ac) and 230 V (ac) must be

applied across the Mix 2 Dem and the Com Dem terminals (27 and 26).

Caution: The same power supply must be used to power the Mix 1 Demand and the

Mix 2 Demand circuits since they both share the Com Dem terminal.

Output Connections

Primary Pump Contact (Prim P1)

The Prim P1 output terminal (16) is a powered output. When the relay in the

control closes, 115 V (ac) is provided to the Prim P1 terminal (16) from the Power L

terminal (14). To operate the primary pump, connect one side of the primary pump

circuit to terminal 16 and the second side of the pump circuit to the neutral (Power N)

side of the 115 V (ac) power supply.
