The thermostat

The thermostat range is 5-35

o

C. Normal working area 

is marked (15-25

o

C). The setting on the thermostat is 

calibrated for a normal room and some experimen-

tation may be required to ind the ideal setting. A 

desired temperature of 20

o

C should be found within 

the marked area. See page 2.

Master/slave function

When installing several radiators, it is possible to use 

one radiator as master and the others as slaves. The 

radiators are then controlled by the irst radiator’s 

thermostat and this gives a more even heat contribu-

tion. A maximum of 10 slaves can be connected to 

one master radiator.

On radiators of model PFE (230V~) the mains 

cable must be exchanged for a special 4-core cable, 

202111. The 230V~ elements have a cable with three 

conductors. For the master/slave function, four con-

ductors are needed. The fourth conductor is used for 

the signal input to/from the thermostats.

When connecting slaves the elements may get 

power from several directions. All circuits must be 

broken before connection terminals are made acces-

sible. 

The master/slave function must be installed by a 

competent electrician. See wiring diagram page 3.

Night temperature setback

Night temperature setback, i.e the possibility to lower 

the temperature at night, can be connected on both 

PFE and PFD. This means that the set temperature is 

lowered 4°C. Night time reduction must be installed 

by a competent electrician. On radiators of model 

PFE (230V~) the mains cable must be exchanged for 

a special 4-core cable, 202111

. The 230V~ elements have a cable with three con-

ductors. For night temperature setback, four conduc-

tors are needed. The fourth conductor is used for the 

signal input to/from the thermostats.

The cable marked NS is connected through the 

time switch to the neutral conductor, see also wiring 

diagrams at page 3.

To change or remove the front panel

The front panel can easily be relacquered or the ap-

pearance changed by applying a plastic ilm.

Disconnect the power before removing the front 

panel, thereafter the two screws under the radiator are 

loosened and the front panel is pulled downwards. 

This must be done by a competent electrician.

Overheat protection

All electrical radiators are equipped with overheat 

protection. The overheat protection is reset by turning 

off the switch for 5 to 10 minutes. To allow the heater 

to cool before resetting the power, remove any ob-

struction causing the unit to overheat. NB. Persistent 

tripping of the overheat protection should be referred 

to a service engineer.

Approvals

•   Models up to 800 W have a low surface tempera 

ture, 60

o

C maximum, and are suitable for use in  

areas where lower surface temperatures are desired. 

•   Protection class: IP23.

•   PFE is approved for mounting with plug or  

  permanent installation 230V~. 

•   PFD is approved for permanent installation  

  400V2~. 

Safety

•   The radiator must not be positioned immediately 

below a permanent socket. 

•   Permanent installation must only be carried out by 

a competent electrician.

•   Do not cover - this can result in a risk of ire!

•  The radiator must not be mounted outdoors.

•  The radiator should be positioned out of reach of  

  people in showers and bathtubs.

•  Radiators for portable use must not be used close  

  to pools, bathtubs or showers.

•  The radiator should be installed to ensure that 

operation and maintenance can be carried out safely. 

•  Before service and maintenance is started, the    

  power must be disconnected and the fan wheel    

  must have stopped.

Maintenance, service and reparation

The radiator should be cleaned when necessary, 

recommended at least twice a year to prevent damage 

on the bearings (differs depending on the indoor 

environment). If the air low is obstructed it may 

also lead to the overheat protection triggering off and 

that the thermostat may be given wrong temperature 

input. Lower the radiator forward. Vacuum the inlet 

grilles on the back and underside. High pressure clea-

ning must not be used to clean the radiator. Cleaning 

must be made carefully and only in exeptional cases 

must the radiator be opened. The radiator must only 

be opened by a competent electrician. The bearings 

are maintenance free and should only be changed 

when necessary. Make sure no discordant sounds are 

heard from the fan. Make sure that the fan wheel is 

not blocked. If the fan doesn’t start after operation 

and/or reset of the overheat protection, contact the 

supplier. A damaged mains cable must only be chan-

ged by a competent electrician.
