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.
MCD4 – The MCD4 thermostat has a built-in programmable time-clock to automatically turn the floor heating system ON and OFF at selected times with the addition of an air sensing option with floor limit mode or floor sensor only. During the OFF periods, the floor does not turn OFF but programs the floor temperature to your selected ‘set back temperature’.When the appears on your screen, the floor is heating. If you see ‘E1’ or‘E2’ there is an error.

Understanding Adaptive Function? ** IMPORTANT FOR HEAT PUMP INSTALLATIONS 
The adaptive function allows the thermostats to predict when the floor heating should be turned on. A thermostat set to 28°C at 6 am will turn on hours before (based on the last few day’s temperatures) in an attempt to be at 28°C at 6 am.

Time of use 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 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 adaptive function on the MCD4 thermostat should be programmed to ‘OFF’.

Benefits of Adaptive Function (for gas installations)
As the weather becomes cooler or warmer, your thermostat will predict what time to turn on your system so your floors will always be warm and at your set temperature, as programmed.
Set the Adaptive Function to ‘Off’ (default setting for MCD4 is ‘ON’)

• Press the MENU button
• Press the ‘Arrow’ button until you see ‘Engineer Settings‘ > Press OK
• Press the ‘Arrow’ button until you see ‘Adaptive Function‘ > Press OK
• Press the ‘Arrow’ button until you see ‘OFF‘ > Press OK
