    8.7 Night Mode If there is a need to reduce the electricity consumption or noise produced by the compressor, e.g. in night-time operation, it is possible to activate the night mode function using an external contact, e.g. a timeswitch (with volt free contacts) connected between terminals 28-29 on the PCB terminal.

  • Page 47: Low Tariff

    8.8 Low Tariff The purpose of this function is to heat any thermal stores and DHW cylinders at a time when electricity rates are inexpensive. This can be achieved by using an external contact, e.g. a timeswitch (with volt free contacts) connected between terminals 30-31 on the PCB terminal. To enable these terminals, parameter 5130 must be set to 1.
