 withtheunit
- Any damage resulting from continued use of the unit despite an obvious defect
- Failure to use original spare parts and accessories
- Use of the device for other than its intended purpose
- Operationaboveorbelowthelimitvalueslistedinthespecications
- Force majeure
- Changes,additionstoorconversionoftheunitarenotpermittedwithout
 writtenpermissionfromthemanufacturer
- Itislikewiseforbiddentoinstalladditionalcomponentsthathavenot
 beentestedtogetherwiththeunit
- If it becomes clear that safe operation of the unit is no longer possible,
for example because of damage to the housing, then turn the controller
 o󰀨immediately
- Any parts of the unit or accessories that are not in perfect condition must
be exchanged immediately
- Use only original spare parts and accessories from the manufacturer.

C.1 Wall installation
Install the controller only in dry areas and under the ambient conditions described
underB.1„Specications“.Carryoutthefollowingsteps1-8.
1.Unscrewcoverscrewcompletely
2. Carefully pull upper part of housing from
lowerpart.
3. Set upper part of housing aside, being
sure not to touch the electronics when
doing so.
4. Hold the lower part of the housing up
totheselectedpositionandmarkthe3
mountingholes.Makesurethatthewall
surface is as even as possible so that
the housing does not become distorted
whenitisscrewedon.
5. Using a drill and size 6 bit, drill 3 holes at
thepointsmarkedonthewallandpush
in the plugs.
6. Insert the upper screw and screw it in
slightly.

Danger
Before working on the unit, switch o󰀨 the power supply and secure it
againstbeingswitchedonagain!
Checkfortheabsenceofpower!
Electrical connections may only be made by a specialist and in comp-
liancewiththeapplicableregulations.Thecontrollermaynotbeputinto
operationifthereisvisibledamagetothehousing,e.g.cracks.
Caution
Low-voltagecablessuchastemperaturesensorcablesmustberouted
separately from mains voltage cables. Feed temperature sensor cables
only into the left-hand side of the unit, and mains voltage cables only into
the right-hand side.
Caution
The customer must provide an all-pole disconnecting device, e.g. a hea-
tingemergencyswitch.
Caution
The cables being connected to the unit must not be stripped by more than
55mm,andthecablejacketmustreachintothehousingjusttotheother
side of the strain relief.
1. Opencontrollerhousing(seeC.1.1)
2. Stripcablesmax.55mm,insert,tthe
