A Comfort Heat floor heating system has been installed in your floor. Underfloor heating will warm you from the floor up giving you an unparalleled feeling of comfort. This heating system is controlled by an electronic thermostat that has a floor sensor for optimum temperature control.
PRIOR TO TURNING ON
The sub-floor and screed have to be fully cured before turning the heating on. For sand & cement screeds you must wait at least 3 weeks before turning on. When turning on the floor for the first time, increase the floor temperature gradually over 2-3 days.

TEMPERATURE SETTINGS
The MICROTEMP RANGE of electronic thermostats is specifically designed for underfloor heating systems. The thermostats are vertically flush mounted and have a 2-pole isolator with a 16A output relay.
MCC2/MCD2 – The MCC2/MCD2 thermostat has a built-in programmable time clock to automatically turn the floor heating system ON and OFF at selected times. During the OFF periods, the floor does not turn OFF but programs the floor temperature appears on your screen, and the floor is heating. to your selected ‘set back temperature’.When the If you see ‘E1’ or‘E2’ there is an error.

BASIC SET UP
Set the date and time when the thermostat is turned on for the first time or reset.
The default setting for MCC2 – floor sensing
The default setting for MCD2 – air sensing
If your thermostat has already been set up but you are not sure if the settings are correct, you can reset your thermostat by pressing a pin into the reset hole for 3 seconds. You will need to then set the time and day as listed above.
Default settings: weekdays
note: thermostat does not “turn off” but changes to a “set back” temperature. This set back temperature can be changed.
MANUAL MODE SETUP
Temporary override of the automatic on /off programmed setting.
The display will flash on the screen and then stop automatically. The thermostat is now in manual mode. To change the thermostat back to automatic mode – press the tick button again
Please refer to our full thermostat manual to program customized settings.

CONNECTING MCC2/MCD2 TO SMART POWER METER
The Smart Power Meter varies the power tariff rate at different times of the day. Overnight the rate is at the ‘Off Peak’ rate and during the afternoon and evenings there is the ‘Peak’ rate. At the times between these, there are ‘Shoulder’ rates. The exact times of these rates should be confirmed by your power provider. As the cost of electricity during ‘Peak’ times is more expensive than during the ‘Off Peak’ or ‘Shoulder’ times the MCC2 thermostat should be programmed to ‘TURN OFF’ when it is ‘Peak’ periods. Following is an outline on how to achieve this arrangement:- Set the Adaptive Function to ‘Off’ – The adaptive function is a program within the thermostat that tries to predict when the floor heating should be turned on to achieve the selected temperature at the ‘Time On’ setting. As this may allow the floor heat to operate during the ‘Peak’ period. Check this function is ‘Off’ in the thermostat program as follows:-
Type MCC2/MCD2 is electronic on/off thermostat for control of temperature by means of an NTC sensor either placed externally or internally in the thermostat. Type MCC2/MCD2 is for flush mounting in a wall socket.

Type MCC2-1991-UA
Mounting of floor sensor (fig. 3) The floor sensor is used for temperature regulation in floor surfaces. For easy replacement, the sensor can be mounted in a tube that is placed between 2 heating cables. The tube is ended towards the floor surface and is sealed. If required, the sensor cable can be extended up to about 100 m with a standard installation cable. 2 leads in a multi-lead cable, which is used as a supply cable for the heating cable, must not be used. Voltage signals may occur which may disturb the thermostat function. If a screened cable is used, the screen must not be earthed but must be connected to the terminal
Type MCC2-1999-UA and MCD2-1999-UA
Mounting of thermostat with built-in sensor (fig. 4) The room sensor is used for comfort temperature regulation in rooms. The thermostat is mounted on the wall with free air circulation about 1.6 m above the floor. Draught, direct sunlight, or any other direct heating outlet must be avoided.
Type MCD2-1999-UA
Mounting of limitation sensor: Max. temperature limitation is used for protection of installation or construction against excessive temperature. The sensor is mounted at a place where excessive temperature may arise. Min. temperature is used for better heating comfort. The sensor is mounted as a floor sensor.
The first time the thermostat is connected, the time and day must be set:
Programming
See the user’s manual.
Fault location
If the sensor is disconnected or short-circuited, the heating system is cut out. The sensor can be checked according to the resistance table Fig. 5.
