Safety instructions and notes on installation
The controller is designed to work with central heating boilers for solid fuels.
q
The controller must be installed by an authorized person.
q
The controller must be connected to a socket with a protective contact.
q
It is required that the boiler had its own safeguards against excessive
q
temperature rise of the boiler caused e.g. boiler controller or related equ-
ipment malfunction.
The controller should be placed in a location that prevents its heating to a
q
temperature higher than 40°C.
The controller must not be exposed to water and conditions causing con-
q
densation (e.g. sudden changes in ambient temperature).
The device should be installed and operated as described in the assembly
q
description and rules for electrical equipment.
A blown fuse due to bad wiring or a short circuit in the electrical system does
q
not constitute grounds for a warranty repair.
Before starting the controller, you should check the electrical connections.
q
The controller is protected with two 2,5 A fuses.
q
Connection of the power cord and fuse replacement should be made with the
q
controller powered off (the controller power plug must be disconnected from
the mains). Connection of the receiving devices and replacement of fuses
with the mains plug of the controller plugged in creates an electric shock
hazard.
The connection cables of the controller can be replaced only by the manu-
q
facturer or their authorized service establishment.
You must not use a damaged controller.
q
Any damage caused by lightning, improper power surges in the power grid or
q
random events are not eligible for warranty repair (please refer to the
warranty terms and conditions).
Notice: Fuses should be replaced only with the controller powered
!
off and the plug disconnected from the mains.
