Installation and operating manual
Item No.: 3182600003
Specifications:
Dimensions: 140mm x 125mm x 85mm
Operational voltage: 230V/50Hz
Control system current consumption: approx.:1.5VA
Switching capacity: max. 2.2kW (AC1)
Protection class: IP 40
Installation:
The controller must be mounted protected against moisture in accordance with its protection class.
Before opening the housing, the device must be switched voltage-free using a multi-pole main
switch with a contact opening distance of at least 3 mm.
Electrical power supply:
The electrical power supply may only be installed by an approved specialist
electrician. The following wiring diagram and the relevant applicable safety
regulations must be observed. The electrical equipment must include a
residual current circuit breaker with IFN=30mA on site.
The sensor cable can be extended up to
10 m in length with a screened cable
(2x0,75mm2). The screen must be
connected to terminal 1. The connection
must be made watertight. The sensor
cable may not be routed alongside power
cables.
Maintenance and service work may only be carried out by an authorised
electrician.
Sensor balance
The electronic temperature regulator and the temperature sensor have been balanced in the works. If
the sensor is replaced, or if a sensor cable is extended, a new balance must be carried out if
necessary using the potentiometers in the controller. Turning the potentiometer clockwise increases
the regulated water temperature. The potentiometer is located on a printed circuit board, to the left
next to the terminals for the temperature sensor (see sketch over page).
