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 programmes to choose from:

• Manual ON/OFF (Constant Single temperature)

• Timer programme (4 timer events/day)
To change from one programme to the other, just touch the intelligent leaf button“

2. MOUNTING AND INSTALLATION

Mounting the Thermostat

The installation of the Green Leaf must be performed by a qualified installer. The Green Leaf is
a thermostat with protection class IP20, make sure to comply with all local regulations when
installing 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

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

(230VAC).

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.
