4.9.5 Pumps, drives 230VAC
Pumps, (heating circuit pumps, hot water charge
pumps) as well as drives (mixing valves, etc.) are
connected directly to the control.
A test-run may only be undertaken on
a fully-prepared system that is ready
for commissioning! (Hydraulics con-
nected, clockwise rotary field ensured)
Smart-Grid
Special instructions for the Smart-Grid function
are available on request.
Utility signal contact
In the case of tariff switching (interrupted power
supply) the heat pump will be temporarily
switched off by the utility.
ATTENTION!
230VAC control voltage is present on
the utility contact.
Fig. 24: Utility signal contact
Remove the bridge on terminal X3 and connect
the cable to the utility contact. If the EVU contact
is interrupted, the compressor and also, if appli-
cable; the auxiliary heater switch off.
Tariff without interruption
In the case of tariff switching without interrupted
power supply the heat pump will be temporarily
switched off by the utility. The control input EVU
on the inside unit is to be used for this.
(Terminal block X3) To activate the function, re-
move the bridge and connect the cable.
Switching off via tariff relay:
For switching by means of a tariff relay (sealed by
the Utility on site) the power supply to the heat
pump compressor is switched off. In this case, the
EVU input is to be switched without fail via an
auxiliary contact on the tariff relay (NC contact).
Off-peak tariff
If the tariff switching takes place in the meter
(Off-peak Tariff), the EVU contact must not be
activated.
