1. DESCRIPTION
The Raychem Green Leaf Thermostat is a Programmable Thermostat designed for Electrical Floor Heating. The thermostat is designed to control your Electrical Floor Heating in order to give you the best possible comfort and the lowest possible energy usage.
The Thermostat can work in 3 different temperature sensing modes:
• Floor Sensing mode
• Room Sensing mode
• Room Sensing mode with floor temperature limiter
The Thermostat has 2 programs to choose from:
• Manual ON/OFF (Constant Single temperature)
• Timer programme (4 timer events/day) To change from one programme to the other,
just press on the intelligent leaf button“
”.

2. MOUNTING AND INSTALLATION
Mounting the Thermostat
Green Leaf is intended for flush mounting in a wall box. It should be positioned approximately 1.5 meters above the floor, protected from direct sunlight and draughts. All electrical conduits passing into the wall box that contain cables must also be sealed to protect the thermostat against draughts, e.g. with a piece of insulation in the conduit outlet.
Step 1: Switch off the power supply Step 2: Detach the metallic support from the
Thermostat using a screwdriver
5
Step 3: Screw the metallic support frame to the in-wall box
Step 4: Install the floor sensor (mandatory for floor sensing mode or room sensing mode with floor temperature limiter). The floor sensor should be installed in a separate flexible conduit all the way to the end, covering the end of the sensor, for easy replacement and to avoid possible signal disturbance on the sensor. For best control performance, position the floor sensor between two heating cables as close as possible to the top floor surface.
Do not position the floor sensor tip closer than 3 cm to the heating cable.
The floor sensor cable can be extended up to 100 m with a separate standard installation cable 2 x 1.5 mm
2
(230VAC).
6
Step 5: Connect the electrical power supply, the sensor and the cold lead of the electrical floor heating system to the Green Leaf according to the electrical diagram. If you connect heating cables exceeding 13A for constant wattage or 10A for self-regulating cables you must use a contactor with an integrated suppression device.
For the earth connection of the floor heating, you must use a separate earth terminal connection block.

Product specific information
The thermostat is compatible with CeraPro, T2QuickNet, T2Blue, T2Red heating solutions.
T2QuickNet
T2QuickNet heating mats are approved with the Green Leaf thermostat working in floor sensor mode. Be aware that the floor sensor must be installed and activated for any installation with T2QuickNet.
T2Red
Self-regulating heating cables have an inrush current when the floor is cold. In order to guarantee the life time of the thermostat, the maximum load of the self-regulating application in nominal conditions is limited to 10A.
A 13A self-regulating load will reduce the life time of the relay contacts.

Floor sensor calibration
The temperature of the floor surface can differ from the temperature measured by the floor sensor due to the floor construction, the floor type and the position of the floor sensor. In order to calibrate your thermostat to this difference you can use the floor sensor calibration OFFSET in installer Menu 4.
After the temperature on the floor is stabilized, place a thermometer on the floor surface in order to sense the real temperature on the surface (Tsurface). Read the floor sensor temperature (Tsensor) on the thermostat and adjust the OFFSET accordingly to the formula:
Tsensor
Tsurface
OFFSET = Tsensor - Tsurface
Room sensor calibration
If the value measured by the room sensor in the thermostat differs from the real room temperature, it is possible to calibrate the room sensor using the installer Menu 5.
After the temperature in the room is stabilized, place a thermometer close to the wall in order to sense the real room temperature. If this value differs from the one shown by the thermostat, adjust Menu 5 using the “
” or the “ ” until the thermostat shows the same
value as the reference thermometer.

7. TROUBLESHOOTING
In the event of damage or malfunction of one of the temperature sensors, the heating output cuts off (fail safe) and an error code is displayed.
Error Code Description
ER1 Short circuit on floor sensor ER2 Open circuit on floor sensor /
Missing floor sensor ER3 Short circuit on room sensor ER4 Open circuit on room sensor ER5 Check sensing mode
The floor sensor can be replaced by a new one. In the event of malfunction of the room sensor, the entire thermostat must be replaced.
The floor sensor has got the following temperature/ resistance values:
Temperature Resistance
15°C 15.8 kΩ 20°C 12.5 kΩ 25°C 10.0 kΩ 30°C 8.0 kΩ 35°C 6.5 kΩ
Error 5 occurs if the thermostat is set in Room Sensing Mode and the floor sensor is installed.
To resolve the error change the sensing mode in Floor sensing or Room sensing with floor temperature limiter. Otherwise, remove the floor sensor to work in room sensing mode.
