Rointe ST.2 Digital Programmable Thermostat
INTRODUCTION
This thermostat is designed to aid in the comfort of your home by providing timed regulation of your heating system. The thermostat is designed to receive temperature input signals from the following sensors:
- Air sensor located inside thermostat.
- Floor sensor installed in floor (see heater instructions for details).
The thermostat is not a safety device and should only be used with Rointe heating products. In order to avoid damaging your flooring the correct floor type must be selected during the thermostat programming process.
WARNING – Important safety note
This product uses mains voltage electricity and work should only be carried out by a qualified electrician. You should always isolate the power supply before attempting to install or repair the thermostat. The thermostat should not be put into operation unless you are certain that the entire heating installation complies with current general requirements for electrical installations. Electrical installation must be in accordance with the latest wiring regulations.
LOCATION
The thermostat should be installed inside a single electrical wall box that is at least 35mm deep. For optimal performance the thermostat should be located in an area with good ventilation. It should not be beside a window/door, in direct sunlight or above heat generating device (e.g. radiator or TV). The thermostat is designed for operation between 0ºC and 55ºC with relative humidity less than 80%.
INSTALLATION
Separate the front housing of thermostat from wall module:
- Unscrew both closing screws (bottom of thermostat) until they will not turn any further.
- Release front housing by gripping lower half of outer frame and pulling outwards.
- Place front housing somewhere safe.
- Run all wires to the wall box. Check to ensure that you have included the following:
- Power (Live and Neutral)
- Heater (Live and Neutral or Switch Live only)
- Floor sensor
- Pull wires through wall box and complete terminal wiring.
IMPORTANT: Ensure that multi stranded wires are fully inserted into the terminals and secured tightly. Any loose strands should be trimmed as they could cause a short-circuit. If connecting more than two heaters, an electricial junction box will be required.
Note: Always ensure that the sensor cable is installed in a separate conduit to the power supplying the thermostat and heating system.
MOUNTING STEPS
- Release the front cover by inserting a screwdriver into bottom crack.
- Take the backing plate apart according to the following diagram.
- Mount the backing plate on the wall socket using a screwdriver.
- After connecting the wires (see connection diagram), mount the thermostat to the backplate and remount the cover and frame.
