5. Electrical Connection
5.1 General remarks, Safety guidelines, warnings:
the cables have to be connected and installed in the
way that the wirings for the thermal contact cannot touch
any energized parts.
if a connected pump doesn't decree a thernal contact,
the intended cables have to be interconnected.
Technical data:
Voltage supply ±5%:
230V/50Hz
the maximum overall performance of all devices
powered by the control unit and the control unit itself:
2300Va
the connection to mains power is to be carried out at the
network terminal X1.
Storage and transportation: -20° C to 60° C
Max. rel. air humidity: 90 % not condensed
Operation temperature: 0-50° C
savings* elC11:
F1 - 2,5T for remaining relay exits
F2 - 6,3AT for relay exit secondary pump
F3 - 6,3AT for relay exit primary pump
F4 - 125 mAT for transformator pre-savings
F5 - 2,5AT for relay exit control valve OPEN / CLOSE
F6 - 1 AT for transformator after savings

●
Before opening the housing, make sure that it is disconnected from the mains.
●
ÖVe and VDe regulations for electrical connections must be observed.
●
electrical installation must be carried out by qualified specialist personnel.
●
A mains power multi-poled circuit breaker must be connected. Rating 16A slow.
●
earthing cable must be properly connected.
●
the water cooler must be supplied with uninterrupted electrical power during operation.
●
Only replace fuses with original fuses (see below).
●
the appliance may only be assembled in a dry room corresponding to fouling degree 2.
●
there must be an easily accessible decollator in the supply current circuit!
●
Warning: only connect and switch the mains power supply on, once the cabling of the primary
and secondary pumps (Pp and Ps) and the modulating control valve is complete and has been
checked!
●
Danger of faulty wiring:
- Danger of an electric shock
- Damage to or destruction of the control unit or the connected devices
●
inspection of the cabling of the primary and secondary pumps:
Check the passage (the measured resistance must always be less than 10 Ohm):
- Connection N at the output of the control unit ← → connection N at the pump
- Connection L at the output of the control unit ← → connection L at the pump
Check the isolations (the measured resistance must always be greater than 1 Mega ohm!):
- Connection N at the pump ← → both wirings for the thermal contact
- Connection L at the pump ← → both wirings for the thermal contact
