This user manual covers following electronic thermostats
MCC2-1991-UA. Incl. floor sensor 3m
MCC2-1999-UA. With built-in room sensor
MCD2-1999-UA. With 2 sensors; built-in room sensor and incl. floor sensor 3m
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.
Type MCC2-1991-UA has an external temperature sensor that is normally placed in the floor construction. In this configuration the thermostat
controls the temperature of the floor and not the temperature within the room.
Type MCC2-1999-UA has a built-in temperature sensor. In this configuration the thermostat controls the temperature of the room.
Type MCD2-1999-UA 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 to high or to 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.

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

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.
Cancel comfort mode
To cancel the override state, press the OK (

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 USD/ kWh
Calculation: (30:100) x 1,2 kW x 0,2 USD / kWh x 24 h = 1,7 USD per day

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 MCD2 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.

Adaptive function:
This function enables the thermostat to calculate when it needs to switch ON so that the required temperature is reached at the set
time. With a start time of 07:00 therefore, the thermostat may switch ON as early as 06:00 so that the desired temperature of 25˚C is
achieved by 07:00. Without this function set, the thermostat will start to heat at the time you set.
