Before you start
Read the entire document
- Installation must be carried out by a certified electrician and must comply with national and local electrical codes.
- To prevent severe shock or electrocution, always cut the power at the service panel before working with the wiring.
- This thermostat should be connected to a circuit equipped with a fuse or a circuit breaker. It must be installed on a certified electrical box.
- Do NOT install the thermostat in an area where it can be exposed to water or rain.
- Install the thermostat on an inside wall facing the heating system.
- Avoid locations where there are air drafts (top of the staircase, air outlet), dead air spots (behind a door), direct sunlight, or concealedchimneys or stovepipes.
- For a new installation, choose a location about 1.5 m (5 ft) above the floor.
- Keep the thermostat’s top and bottom air vents (openings) clean and unobstructed at all times.
About your thermostat
The thermostat provides three temperature control modes:
| A mode: | • controls the ambient temperature |
| F mode: | • controls the floor temperature |
| AF mode: | • controls the ambient temperature and limits the floor temperature |
See page 8 on how to select the temperature control mode setting.
Supplied Parts
- One thermostat
- One floor sensor (for AF and F models only)
- One wall plate (optional, in some countries only)
Controls
* Use this switch to disable heating (e.g. in the summer).
Installation
- Turn off power to the heating system at the main electrical panel.
- Loosen the bottom screw and remove the thermostat’s faceplate from the power base. The screw cannot be completely removed.
- Before making the connections, make sure that the power base covers the electrical box entirely. If not, install the supplied wall plate at the back of the power base.
- Connect the wires (see page 6).
- Push wires into the electrical box and secure the power base to the electrical box. The head of the screw must be less than 2 mm thick.
- Select the control mode (see page 8).
- Set the minimum and maximum temperature limits (see page 9).
- Install the faceplate on the power base.
- Return power to the heating system.
Connections
| Power | Terminals 1 & 5 |
| Load | Terminals 2 & 4 (see note 1) |
| Pilot Wire | Terminal 3 (see note 2) |
| Floor sensor | Terminals 6 & 7; no polarity (see note 3) |
NOTE 1 If a contactor is used between the thermostat and the load, install a snubber at the contactor’s coil terminal to ensure the proper operation of the thermostat.NOTE 2 Optional (see page 10).NOTE 3 For the proper operation of the thermostat, the floor sensor must be centered between two heater wires having a maximum temperature of 80°C (176°F). The floor sensor wire must not cross any heater wire or be placed close to it.NOTE 4 Ensure that the wires are tightly secured to the terminals. Apply a minimum torque of 0.5 Nm (4.4 Lb/in) when tightening the screws.NOTE 5 The terminals are designed to handle a cross-section of wire measuring 0.33 to 3.1 mm2.
Control mode
Position the switch, on the back of the thermostat faceplate, according to your application.
| Type | SwitchPosition | Application |
| A | Up | Controls the ambient temperature |
| F | Down | Controls the floor temperature |
| AF | Up | Controls the ambient temperature and limits thefloor temperature |
Minimum and maximum limits
Use two potentiometers on the back of the thermostat faceplate to set the minimum and maximum temperature limits. Use a flat-tip screwdriver to rotate the potentiometers until the notch points to the desired temperature limit.
Depending on your application, the potentiometers limit the following temperature:
- ambient temperature (A)
- floor temperature (F or AF)
