APPLICATIONS

Heating only (On/Off or OpenTherm boiler) or Heat/Cool (2-pipe system)

• The receiver provides single output control when paired with Unisenza Plus Thermostat or Unisenza PLUS Electronic Thermostatic Head.

• If there is no OpenTherm (OT/+) connection, the control output will go through the On/Off relay.
  The Aux Relay will be in-sync with the Main relay for the interlock of additional equipment such as the circulation pump

• If the unit detects an OpenTherm (OT/+) connection, the control will be taken over by the integrated OpenTherm controller automatically. It can be paired with the Unisenza Plus Thermostat and work together as an OT master unit.

Central Heating plus Domestic Hot Water (S-plan or Y-plan)

• The receiver provides two output controls. Main Relay controls Central Heating, and Aux Relay controls Domestic Hot Water.
• It is paired with a thermostat supporting both heating and DHW function, such as the Unisenza Plus Thermostat .

Heat/Cool Independent system (4-pipe system)

• The receiver provides two output controls. Main Relay controls Heating, and Aux Relay controls Cooling.
• It is paired with a thermostat with heat/cool manual changeover functions, such as the Unisenza Plus Thermostat.

Dual Zone Controls

• The receiver provides two on/off output controls. Main Relay controls Zone 1 and Aux Relay controls Zone 2.
• It is paired with two zone thermostats with each controlling the heating or cooling in the zone individually.
• Pairing with multiple Unisenza Plus Thermostats or Unisenza PLUS Electronic Thermostatic Heads for boiler interlock is supported for Zone 1 only.
• A maximum of 16 devices including Unisenza Plus Thermostat and Unisenza PLUS Electronic Thermostatic Head can be paired with the Unisenza Plus Receiver.
