External Control; Peak / Off -Peak Hours Contact; Electricity Provider Contact - Dimplex Edel 200 WATER/3 Installation Manual

5.4.2 - External control

Only an external connection using a
voltage free «dry contact» is authorised,
otherwise there is a risk of damaging the
electronic circuit board.
It is discouraged to operate the Heat
pump during peak hours so as to
optimise its operation.
It is not necessary to connect the electricity metre's timer switch
to program the heat pump water heater for peak/off -peak time
operation.
The appliance's control panel can be used to program time slots for
the heat pump water heater or for the electrical back-up to run (see
§ «Programming» for daily programming options).

5.4.2.1 - Peak / Off -peak hours contact

It is also possible to connect the electricity provider dry contact to
the heat pump water heater without using programming.
- Contact open
- Contact closed
The load shedding level can be selected and programmed for the
appliance (see § «Load shedding»).
By default, the electrical back-up does not run during peak hours.
To access the electrical connections:
• Remove the cover and the shell.
• Remove the cover of the appliance by taking out the screws which
fi x the shell onto the lower part of the appliance.

5.4.2.2 - Electricity provider contact

To prevent the electrical back-up from running during peak hours,
connect the dry contact originating from the electricity counter,
to terminal 1.
- Contact open = Back-up not allowed to run
- Contact closed = Back-up allowed to run
By choosing load shedding level 0 or 1 (see § «Load shedding»), you
stop the electrical back-up alone from running (load shedding =1)
or the heat pump and the electrical back-up from running (load
shedding = 0).
• Pass a 0.75mm² 2-wire cable with metal tips through a cable
gland at the back of the appliance and bring the end of the cable
around to the electronics board. The other end of the cable should
be connected to the timer switch.
• Insert the 2-wire cable through a grommet from the electronics
box.
• Connect the 2-wire cable to «Input 1» indicated on the electronics
board, having removed the existing red bridge beforehand.
