Dimplex WPM Touch Heat Pump Manager Installation Manual

Quick guide from the manual

The WPM Touch is a heat pump manager designed for wall mounting. It must be installed in a dry room with an ambient temperature between 0°C and 35°C. Ensure no condensation forms on the device. The unit requires a continuous power supply to maintain frost protection functions.

Mounting the heat pump manager

The controller is attached to the wall using the 3 screws and dowels (6 mm) included in the scope of supply. Follow these steps for installation:

• Open the controller cover.
• Mount the dowels for the upper fastening eyelet at operator level.
• Screw the screw into the dowel so the controller can be hung.
• Mount the controller by the upper fastening eyelet.
• Mark the position of the side drill-holes.
• Unhook the controller, mount the side dowels, and remount the controller to tighten all screws.

Temperature sensors

The system uses NTC-2 and NTC-10 sensors. The outside temperature sensor (R1) is NTC-2. Other sensors (heating circuit, domestic hot water, demand, renewable cylinder) are NTC-10. Sensor cables can be extended up to 40m (or 50m with 2 x 0.75 mm cables) and should not be installed next to power cables.

Strap-on sensor installation:

• Remove paint, rust, and scale from the heating pipe.
• Coat the cleaned surface with heat transfer compound.
• Attach the sensor with a hose clip and thermally insulate.

Electrical installation

The electrical supply cable (L/N/PE~230 V, 50 Hz) must have a continuous voltage and should be tapped upstream from the utility company blocking contactor. An all-pole disconnecting device with a contact gap of at least 3 mm must be installed.

Key wiring requirements:

• Utility blocking contactor (K22): Connect the NO contact (13/14) to pin (1) (=DI1) of function block 0.
• Immersion heater (E10): Controlled via pin (7) (=NO3) of function block 0.
• Circulating pumps: Connect the heat circulating pump (M13) to pin (5) and (8) of function block 0.
• Caution: Extra-low voltage is present at adapter boards -N1/SL, -N1/ML, -N17/LV. Connecting line voltage to these terminals will destroy the manager.

Functions and pin assignment

The WPM Touch has a fixed pin assignment for the "General/1st unmixed circuit" on the grey function block. Additional functions can be assigned to three flexible function blocks (yellow, green, red). If more are needed, two further blocks (orange, blue) can be added via expansion accessories. During commissioning via the touch display, the function and color assignment are queried and set.

Special accessories

The manager supports the RTM Econ room temperature controller for cooling regulation. It can also be connected to a building management system via EIB, KNX, Ethernet, Modbus TCP, or Modbus RTU.
