Documents

  • pre-assembled, tightness-tested and heat-insulated assembly
  • compact design
  • robust mixer with adjustable flow coefficient Kvs from 12 to 22 m3/h
  • available with high energy efficiency pumps class A and high-grade, robust mixer as well as actuator
  • easy, fast mounting

Heating pump assembly for use in non-mixed heating circuits. It connects the heating boiler and the pipe system. With the 3-way mixer KVS Vario and the actuator, the flow temperature can be adjusted to a desired temperature by adding water from the return. PrimoTherm® 180-2 can also be used to increase the return temperature with solid fuel boilers which have a controller for increasing the return temperature. The opening temperature must be set at this controller.

Complete, pre-assembled and tightness-tested heating pump assembly with all required functional components, form-fit insulation and wall mounting unit.
The Flow line consists of:
Combination valve with thermometer in the hand wheel (red mark, range 0/120 °C)
3-way mixing valve ARV 325 KVS Vario with adjustable flow coefficient Kvs and ProClick adapter system
Maintenance-free, silent actuator ARM 343 (6 Nm, 120 s, AC 230 V) with 0/90° angle of rotation, indication for direction of rotation, selector key "Manual/Automatic Mode" and ProClick adapter system
System connection G1¼ female (heating circuit)
Suitable for pumps with 2" x 180 mm.
The Return line consists of:
Combination valve with thermometer in the handle (blue mark, range 0/120 °C), pipe for length compensation with gravity brake
System connection (boiler) G2 with screw connection G1¼ female (easy mounting and adapter G1½ AB for use with boiler manifold)
