1. Applications

The easy 3p electronic clock thermostat is designed for

room temperature control in conjunction with:

•

heating systems, e.g. hot-water heaters, convector hea-

ters or floor heating

•

electric convector heaters, ceiling and storage heating

•

night-storage heaters

•

circulation pumps

•

burners and boilers

•

heat pumps, etc.

•

Airconditioning applications (cooling only)

➩ other temperature controllers can be controlled

via time switch output.

very simple operation

•

comfort and setback temperature adjustable

•

3 operating modes for:

➩ permanent comfort temperature (5…30°C)

➩ permanent setback temperature (5…30°C)

➩ clock mode (automatic)

•

Indicator lamps for:

➩ heat demand

➩ setback mode

•

time switch output (for temperature setback of other

temperature controllers)

•

available with daily or weekly timer

•

•

new design

2. Function description

The clock thermostat is designed to control the room tem-

perature.

In the automatic mode, a changeover is effected between

comfort and setback mode by the built in timer.

In setback mode the green indicator lamp lights up.

If room temperature drops below set value, heating will

start, the red indicator lamp will light up.

Indicator lamps

Red indicates when controller demands heat,

Green indicates when setback mode is activated.

Red flashing for failure.

Operating voltage to be switched OFF and ON again.

Temperature setback of other temperature

controllers

Temperature setback inputs of other temperature control-

lers can be connected to time switch output (terminal 28).

They are then controlled by the time switch.

The position of the mode selector switch (see 6.6) influen-

ces this output accordingly.

Controller heat demand at PWM

If room temperature drops below the set value, heating

mode will start. The controller output is in the form of pul-

ses of varying length (PWM). The length of the pulses

depends on the difference between set and actual room

temperature.

The sum of pulse and pause times can be selected with

J4 (between 10 or 25 min.).

If there are large temperature differences, the controller

will switch ON or OFF permanent, e.g. when changing

over to temperature setback mode. Use PWM only at

current ≤10 A.

Fig.1: Characteristic of impulse pause ratio depending on temperature

Cycle time setting

For inert applications (e.g. burners) we recommend the

long cycle time.

For quick applications (e.g. electric direct heaters) we

recommend the short cycle time.

Heat demand of the controller at ON/OFF regulation

When room temperature drops below set temperature the

output will be switched on, whereas it will be switched off,

when set value is exceeded.

6. Operation

Temperature setting

Comfort temperature (daytime temperature)

is set by means of externally visible setting knob (1)

Setback temperature (night temperature)

is set by means of adjustment knob (2) beneath

cover.

Time setting

by putting one finger on dial (3) and turning in any

direction, you can set the time.

Arrow (4) points to the selected time.

Switching time setting

Bring movable tappets (5) into required position

using a pointed object.

Outer ring = comfort temperature

Inner ring = setback temperature

Mode selector switch (6) – internally
