GAHP Controls
The Buderus GWPL 38 is designed for properties where the heating system is controlled by a Building Management Systems (BMS).
The BMS will communicate the required heat input to the GWPL control using a 0-10V or volt free enable signal and there is an output for operational status.
The GWPL control system ensures the efficient, reliable and safe operation of the heat pumps and will be provided as part of the supplied system.
It also provides information required for maintenance and service.

Two main parts
The supplied GWPL control system is made up of two main parts:
the programming and sequencing unit (GHMC20) and the BMS interface module (GHMC20T).

GHMC20
The programming and sequencing unit, GHMC20, controls systems with up to sixteen heat pumps, regardless of how these are configured.
The controller will automatically recognise all connected heat pumps and communicates with them using CAN-bus.
Where the BMS cannot provide weather compensated control, the GHMC20, fitted with the optional sensor, can provide this to further improve operating efficiency. |

GHMC20T
The BMS interface module, GHMC20T, manages communication between the GHMC20 and the buildings BMS.
It provides separate inputs from the BMS for heating and hot water from the BMS allowing either prioritisation of heating or hot water or for both to operate in parallel. |

Installation
Both of these should be installed in an electrical switch cabinet, ideally close to the BMS.
This allows access to the controls for monitoring without having to access the heat pumps which will be installed externally.
