Whilst the thermostat is operating in any of the modes above, the temperature can be manually altered by pressing the + or –buttons. The set
temperature will then revert back to the pre-set level at the next change of mode.
Date & Time Settings
To set the correct date & time press and hold for 3 seconds. Minutes will flash, press + / –to alter. Press once again to alter hours (24 hour clock).
Press once again to change week day. The numbers from 1 to 7 at the top of the screen represent Monday to Sunday.
7 Day Automatic mode
To select the 7 day timer mode press M until is displayed on the LCD screen. The thermostat will then switch between comfort & energy saving
mode (On/Off) automatically according to the day & time settings. Each day of the week can be programmed with individual settings.
To set up the automatic mode, press & hold for 3 seconds. To select the day of the week to be programmed press .
The bottom of the screen will show the following pattern of 24 numbered squares. Each square represents a 1 hour period of a 24 hour cycle. Each of
these 1 hour periods can be programmed to comfort or energy-save (On/Off) mode.
To make changes to the timed program, press + / –to select the 60 minute period. Then press to select the mode.
Pressing + or –will copy the selected mode from the previous 60 minute period.
Whilst programming, inactivity of 5 seconds will save the settings entered & the thermostat will return to normal operational mode.
Advanced Settings
To enter advanced settings press and hold Mfor 3 seconds. Press Monce again for each numbered function.
1. Temperature Calibration. If an accurate temperature read out from the room or floor differs from the read out on the thermostat, providing the
sensor has been checked against the stated resistance values, the thermostat can be calibrated using this function. The range is -8˚C ~ +8˚C
2. Sensor Selection. See beginning of the Operating Instructions section for details.
3. When operating the thermostat with the rFS sensor selection, the room temperature will display on the thermostat. This function allows the
user to see the current floor temperature.
4. When operating the thermostat with the rFS sensor selection, this function allows the user to amend the maximum temperature the floor can
reach. If the floor temperature exceeds this over-heating protection set-point, ALARM will flash on the screen and the heating output will cut
out.
Safety Information
WARNING: RISK OF ELECTRIC SHOCK. Disconnect power supply before making electrical connections. Contact with components carrying hazardous
voltage can cause electrical shock and may result in severe personal injury or death.
This thermostat is not a safety device and should only be used with safety certificated floor heating systems suitable for their specific purpose. In order to
avoid damaging your flooring, ensure the correct sensor selection & operating temperatures are selected during the programming process.
Thermostat Load and Contact Life:
We strongly recommend that you do not load the thermostat to the full extent of its 16A relay contact rating. It is good practice to restrict the load to
2kW~2.4kW (10A~12A). The relay is rated according to the requirements of EN 61810-1:2004 and EN60730-1 which are not representative of 'real life'
applications but an arbitrary test method. Critically, relay contact life is affected by loading. At 10A~12A the contact life is more than double its life at 16A.
In addition, measurement accuracy and control of room temperature is optimal at loads below 2kW~2.4kW. The relay contacts have resistance
proportional to current passed and greater currents cause greater losses across the relay contacts. These losses can increase the internal temperature of
the thermostat and affect the internal sensor used for air temperature control.
