2 Description of controller 2 2.2 About the controller The Heat pump controller WPC 5 facilittes efficient use and function control of your heat pump and heating system. The device is impressive most of all for its functionality and simple, almost self-explanatory operation. For each step in the input process the individual entry keys are assigned to appropriate functions and explained. The controller menu contains headwords for the measured values and settings, as well as help texts or clearly-structured graphics. The WPC 5 can be used as a heat pump controller for the various system variants...

2 Description of controller 2 2.5 Hydraulic variants The following illustrations should be viewed only as schematic dia-grams showing the respective hydraulic Systems, and do not claim T Caution to be complete. The controller does not replace safety devices under any circumstances. Depending on the specific application, additio-nal system components and safety components may be mandatory, such as check valves, non-return valves, safety temperature limiters, scalding protectors, etc., and must therefore be provided. 2 Hydraulic variant / program 1 Heat pump with heating circuit Hydraulic variant...

3 Installation 3 3.1 Wall installation Install the controller only in dry areas and under the ambient conditions described under 2.1 ̈́Specifications". Carry out the following T Caution steps 1-8. Fig. 3.1.1 1. Unscrew cover screw completely 2. Carefully pull upper part of hou-sing from lower part. 3. Set upper part of housing aside, being sure not to touch the electronics when doing so. 4. Hold the lower part of the hou-sing up to the selected position and mark the 3 mounting holes. Make sure that the wall surface is as even as possible so that the housing does not become distorted when it is...

3 Installation 3 3.2 Electrical connection A Before working on the unit, switch off the power supply and secure it against being switched on again! Danger check for the absence of power! Electrical connections may only be made by a specialist and in compliance with the applicable regulations. The controller may not be put into operation if there is visible damage to the housing, e.g. cracks. A Low-voltage cables such as temperature sensor cables must be routed separately from mains voltage cables. Feed temperature caution sensor cables only into the left-hand side of the unit, and mains voltage...
