For the property owner

9.5.2.3 Elec. heater

In the “Elec. heater” menu you can make settings

affecting the operation of the immersion heaters.

El.heater upper kW 9 (0,3...18

Here you select the power that the upper immersion

heaters are allowed to emit.

El.heater lower kW 9 (0,3...9)

Here you select the power that the upper immersion

heaters are allowed to emit

El.heater lower °C 50(30...60)

Setting of temperature for the lower immersion heater.

The lower immersion heater is only allowed to operate

when the heat pump is blocked for some reason.

Delay mixing valve 180(30...240)

This is where the mixing valve delay is set - the period

before it draws energy from the upper part of the

tank. The mixing valve can be blocked so that it never

retrieves energy from the upper part of the tank.

Main fuse A 20 (16...100)

The property’s main fuse size is set here. This setting and

the ﬁtted current sensors ensure the fuses are protected

when using appliances which generate temporary power

peaks, for example, cookers, ovens, engine heaters etc.

The product temporarily reduces power drawn where

this type of equipment is being used.

Conversion factor curr. sensors 1:1 (1...10)

This menu contains the factor the current sensor are to

use. This setting is only performed if the connection has

been installed for a current sensor for higher currents.

Example: User (set) value 2 => 16 A will be 32 A.

Tariff El Off (Off/On)

This indicates whether the product is connected to tariff-

controlled electricity.
