1. Getting started

Introduction

The thermostat is capable of switching on your heating system at pre determined times on different days of the week. It is possible to set 4 periods called
events each day with different temperatures. From factory a default schedule is programmed suitable for most installations. Unless you change these
settings the thermostat will operate to this default program.

Working with lower temperatures during times that the room is unoccupied will lower your energy costs without reducing the comfort. The thermostat has an
adaptive function that automatically changes the start time of a heating period so that the desired temperature is reached at the time that you set. After 3
days the adaptive function has learned when the heating must be switched on.

The thermostat has a built-in temperature sensor and an externally temperature sensor. In this configuration the thermostat controls the temperature within
the room and use the externally temperature sensor as limit sensor avoiding too high or too low temperatures in the floor construction.

The thermostat has a pin button marked R, allowing you to reset the thermostat to factory settings. These are listed at the end of this manual with space for
you to record your own weekly schedule.

The display is backlit when operating the buttons. The heating element is switched off when the light is on in the display.

The heating system can be switched off on the built-in interrupter. The Microprocessor taking care of the time will still be supplied with power whereby time
and day will be maintained. When the heating is required and the thermostat is switched on, it will continue the 4-event programme based on present time
and day.

Setting the thermostat into operation

Press the UP ( ) or DOWN ( ) buttons to
select the correct time and press OK button ( ).

Then press the UP ( ) or DOWN ( ) button to
select the correct day and press OK ( ) button.

First time power is connected the clock and day will be flashing and must be set. If you need to
adjust the time of the thermostat at a later date, insert a pin into the hole for setting of time
and day. Adjustment must be made for summer and winter time.

2. Daily use of the thermostat
4-event clock mode

The day has been split into 4 events describing a typical day. When the thermostat is in 4-event mode it will automatically adjust the temperature according
to the required temperature to the required time. As standard the thermostat has 5 days with 4 events, and 2 days with 2 events. Programming see 3.

Temporary override

To temporarily override the temperature in the 4-event schedule program, press the UP ( ) or DOWN ( ) button
once, to show the temperature, and press again to increase or decrease the temperature. The display will flash for
5 seconds, and will then revert to the time. The override will operate until the next programmed event when the
unit will resume the automatic programme.

The clock function symbol ( ) and one of the 4-event symbols ( ) will be indicated.
Programming see 3.

Cancel comfort mode

To cancel the override state, press the OK ( ) button twice.

Permanent override:

During holidays, the scheduled 4-event program can be overridden.
Press the OK ( ) button, and then the UP ( ) or DOWN ( ) button until the override temperature is set.
The unit will now operate to this temperature permanently.

Cancel manual mode

To cancel the permanent override state press the OK ( ) button once, and the unit will resume automatic function.

3. Programming
4-event time and temperature

For each event, the start time and required
temperature must be set.

For example, in the morning you wish the heating to
start at 07:00 and the temperature to rise to 21˚C.
Press OK ( ) button for 3 seconds and the start time
is displayed. Change this to 07:00 with the
UP ( ) or DOWN ( ) button. Press OK ( ) to confirm.
The temperature is now displayed. Change this to 21˚C
with the UP ( ) or DOWN ( ) button.
Press OK ( ) button to confirm. This action can now
be repeated for the second event.

These settings will be valid with days 1-5 showing on
the display. To program the days 6 and 7, repeat the
above. Days 6 and 7 are usually Saturday and Sunday,
and only have two events.

The temperature can be set within the range of +5 to
+40˚C. It is also possible to select the heating OFF at
that event by reducing the setting to 5˚C, and then
pressing the ( ) once more.

Monitoring of energy consumption

The thermostat calculates average time it has been switched on allowing you to monitor your energy consumption.
In the thermostat you can read out:. Total switch-on time in percentage in the latest 2 days, 30 days or 365 days.

Calculation of operational costs per day: (switch-on time:100) x kW x kWh-price x 24 h per day
Example: Read-out: 30 % in the latest 365 days

Size of heating system: 1,2 kW (ask the installer)
Cost of power: 0,2 EUR / kWh
Calculation: (30:100) x 1,2 kW x 0,2 EUR / kWh x 24 h = 1,7 EUR per day

4. Advanced settings and read-out

4-event sequence

The present event sequence flashes: Days 1-5, followed by days 6-7. To change, press the UP ( ) button until you have days 1-6
and then day 7 flashing, or all 7 days are flashing. Select the required sequence with the OK ( ) button.

Max and min allowed temperature range. The temperature setting range of +5˚ to +40˚C can be limited to prevent a too high or too
low temperature being selected under manual or comfort mode. For OCD3 with limit sensor the max. and min. temperature range refer
to the temperature of the limit sensor. For example: A wood floor covering should not be allowed to exceed a maximum of 27˚C. Low
limitation is used where the temperature of the floor is required never to fall below the minimum set temperature.

Selection of type (only visible in type OCD3)

Type OCD3-1999 has a built-in temperature sensor and an externally temperature sensor. In this configuration the thermostat controls
the temperature within the room and use the externally temperature sensor as limit sensor
Type OCD3 can be changed into type OCC3-1991 with an external temperature sensor that normally is placed in the floor construction.
In this configuration the thermostat controls the temperature of the floor and not the temperature within the room. OCD3 can also be
changed into type OCC3-1999 with a built-in temperature sensor. In this configuration the thermostat controls the temperature of the
room, and the external temperature sensor should not be installed.
