Handleiding

1. Use and Application

Temp. Range 10…60°C

• direct floor heating

• floor storage heating

• surface heating

• air conditioning etc.

2. Installation instructions

The cover (14) of the timer housing should be lifted up. After remo-

ving the setting knob (13) for the daytime temperature setting (1) and

loosening the fixing screw (3) the upper part can be turned in the di-

rection of the timer and removed.

The floor heating thermostat can then be fitted to any commercially

available flush-mounted socket with horizontal fixing holes or alter-

natively directly onto the wall. When selecting a suitable place for mo-

unting, draughts and warm air currents should be avoided, and you

should allow a free circulation of air. Recommended mounting height:

approx 1.5m

3. Wiring Diagram

Important Notice:

Please read carefully the technical data on the inside of the cover of

the equipment.

Insert insulated wires in corresponding screw terminals and connect

as shown in the wiring diagram. Once the electrical connection has

been made replace the upper housing and screws in (3), and replace

the daytime temperature setting button (13).

4. Changeover setting. Temperature set-back

For daily programme Model 52527

First lift off cover (14).

Set-back temperature ”on“ = blue tappet

Set-back temperature ”off“ = red tappet

The tappets are factory set to come at 22.00 and switch off at 06.00.

These times can be changed if required by adjusting the tappets. The

tappets are pressed upwards and can be moved around the dial until

the disered switching times are set.

For the weekly programme Model 52528

Procedure is as for setting the daily programme. Note the following

abbreviations for the days of the week:

Beginning with Mo = Monday, Di = Thuesday, Mi = Wednesday, Do =

Thursday, Fr = Friday, Sa = Saturday, So = Sunday.

The minimum time setting is one hour.

5. Setting the timer

For the daily programme

To set the timer first remove the cover (14). Set the time by turning

the minute hand clockwise. Take care to ensure that the indicator ar-

row (11) next to the day dial (8) is showing the setting time on the

dial.

Example

Setting time = 15.00

Turn the minute hand until the number 15 on the 24 hour dial is at

the indicator arrow.

For the weekly programme

To set the timer first remove the cover (14). Set the time by turning

the minute hand clockwise. Take care to ensure that the indicator ar-

row (11) is showing the set time on the week dial. Take care that the

correct day of the week as well as the time is indicated.

Example:

Setting time = 15.00, Tuesday

Turn the minute hand until the number 15 and Di are the indicator

arrow on the week dial.

6. Recommended day and night temperature settings

The temperature, which you can require in the living area, is set by

means of the daytime temperature setting knob (13). A setting on the

red point is recommended, corresponding to a room temperature of

approx. 20 deg C. The night set-back temperature can be set by me-

ans of the adjustable potentiometer (2). It is recommended to set a

set-back temperature of approx. 3 to 4 K. Naturally other settings are

possible, if required.

7. Problems – Timer

No night set-back: are the switches set for the correct time? Is

the setting sequence correct for 2 or more heating programmes

– red-blue – red-blue?

Is the position on the setting knob correct?

8. To reduce the setting temperature range of the

daytime temperature

The room temperature setting knob is factory set on the Range 1…6.

See illustration 2. On the underside of the setting knob there are 2 re-

stricting rings, with a setting range of 5…35 deg C. When narrowing

the setting range please do so in accordance with the following dia-

gram.

Reducing the range in the setting knob.

Using the restricting rings you can narrow the setting range as desi-

red, for example within the range 3 to 5

Range stops inside setting knob

8.1 Setting procedure

• First select the desired limits:

Example Upper: 5 Lower: 3

• Caution:

First switch setting knob to approx. the middle of the desired

setting range.

Example:

Mid point of 3 and 5 is ●

• Then remove the setting knob to ● and remove.

• Set red setting ring to upper temperature limit:

To set upper limit to 5

Turn anti-clockwise. Note: instructions refer to the outer num-

bers of the scale.

Insert tip of ball point pen into hole and turn red ring left on to 25

deg C (max scale) (see diagram). Illustration 3.

• Set the blue setting ring to

lower temperature limit:

To set lower limit to 3.

Turn clockwise. Instructions refer to the inner numbers of the

scale.

Insert tip of ball point pen and turn blue ring onto 15 deg C. (min

scale) (see diagram). See illustration 4

• Replace setting knob with setting at

●.

The indicator should now show the middle of new setting range:

see Point 2.

Operating Instructions

for floor heating thermostat

with quarz timer

Model 52527 and 52528

Caution

If replacing an existing thermostat, Model 52521, using the old

sensor (Colour Code:black) R18 must be disconnected (by coun-

ting one leg of the resistor).

Caution

The unit should only be installed and set up by an qualified en-

gineer. The enclosed safety precautions should be observed.

Other application options, dimensions & in particular technical

specifications are given in our information sheet.

The floor heating thermostats are fitted with suppressors in accor-

dance with VDE 0875-A2 and EEC Guidelines 82/499/EWG rela-

ting to radio inteference grade N.

If the unit is used in combination with other appliances, care

should be taken in case any of the appliances causes radio interfe-

rence. Installation must be in accordance with the appropriate re-

gulations.

Caution:

• The switch in the thermostat breaks the circuit but not

the hea-

ting resistance

• If an auxiliary circuit is used the mains voltage should be swit-

ched off (remove fuse)

• In the event of a sensor disconnection or sensor short circuit the

relay contact is not engaged; nor in the event off an appliance

breakdown. The Thermostat is self monitoring.
