1 Safety instructions and explanation of symbols
1.1 General safety instructions
About this manual
This manual contains important information about the safe and correct installation and operation of
the solar heating programmer.
This manual is intended for heating engineers.
BRead this manual carefully and keep it for future reference.
BAlways observe the safety instructions to prevent injury and damage to property.
Intended use
The solar heating programmer (referred to from now on as the programmer) may only be used for
operating solar heating systems under the permissible ambient conditions
( ÆSection 2.4).
The programmer must not be used outdoors, in damp rooms or in rooms where easily combustible gas
mixtures could form.
BOnly operate the solar heating system as intended and when it is in perfect working order.
Electrical connections
Any work that requires the programmer to be opened may only be carried out by a qualified electrician.
BThe electrical supply must be connected by a qualified electrician.
BMake sure that an all-pole mains isolating device compliant with EN 60335-1 for disconnection from
the power supply is fitted.
BIsolate the programmer from the mains power supply before opening.
Domestic hot water temperature
BTo limit the domestic hot water temperature to 60 °C max., fit a hot water blending valve.
Standards and guidelines
BEnsure that installation and operation of the device conforms to the local standards and guidelines.
Disposal
BDispose of packaging in an environmentally responsible manner.
BWhen replacing components, dispose of the old parts in an environmentally responsible manner.
