Explanation of the high voltage connections.
1-2-3-PE DO NOT USE
Do not connect wires to these terminals
4-PE-5 DO NOT USE
Do not connect wires to these terminals
6-PE-7 GENERAL or WATER HEATER PUMP
Connections for the power supply of a water heater pump. (P1, see chapter
8.5
for detailed electrical specifi-
cations).
8-9-PE-PE MAINS SUPPLY
The power supply connection of the unit. 8 = Line voltage wire; 9 = Neutral wire, PE = Ground wire
10-11 ALARM RELAY
A semiconductor alarm output. This is a triac output with an active voltage of 120 VAC, it can only handle
resistive loads between 5 and 50 Watt. E.g. an incandescent bulb of 10-50 watt can be added to this.
This alarm will be activated 60 seconds after an error has occurred.
There are a few exceptions:
- Alarm output will not be activated for a service warning;
- Alarm output will not be activated for warning 202 (Appliance selection).
10 = Phase wire; 11 = Neutral wire
PARAMETER: water heater parameter 127, see: 11.9 "programmable in- and outputs"
X1-X2-X3 HIGH POWER IGNITER (external igniter)
A separate connector for an external igniter is located on the cable tree, near the water heater controller and
labelled "High power ignitor". This is a connection for an external ignition transformer. Instead of the internal
igniter, an external igniter can be connected. Available as an accessory, see § 5.1 "Accessories".
X1 = Neutral wire; X2 = Ionization; X3 = Line wire.
PARAMETER: water heater parameter 126, see: § 11.10 "programmable in- and outputs".
To all outputs following applies: maximum current 2 Amp each output.
Total output of all currents combined maximum 3.5 Amp.
The inrush current of the 3-way valve and/or pumps is maximum 8 Amp.
