3 Description
3.1 General description
The MIT module is fitted with a DIEMATIC iSystem control panel with
integrated regulator. It handles the automatic operation of the heat
pump as a function of:
4The outside temperature.
4The ambient temperature when the remote control (as an option)
is connected.
The DIEMATIC iSystem control panel enables:
4The independent control of a direct circuit without mixing valve and
a circuit with mixing valve.
4The independent control system on a DHW preparation circuit.
4Anti-freeze protection for the installation and the environment if the
home is empty (This period may be programed up to 99 days).
The MIT module also integrates the 30-litre buffer / pressure release
tank and additional electrical heating (Only MIT/E).
