SOLO 400-632-000-A 2008-09-19 1/7 The SOLO thermostat is designed to control the temperature of a floor heating system for both 120-volt and 240-volt applications. The thermostat can be used to control either the floor temperature or the ambient temperature. It has a maximum load capacity of 15 A (1800 W @ 120 VAC or 3600 W @ 240 VAC). SUPPLIED PARTS • One (1) thermostat • One (1) floor temperature sensor • Four (4) solderless connectors • Two (2) 6-32 mounting screws • One (1) flat-tip screwdriver OPTIONAL ACCESSORY (SOLD SEPARATELY) • Honeywell outdoor sensor AC629 (for outdoor temperature and humidity readings). Refer to section 10. TURN OFF POWER TO THE HEATING SYSTEM AT THE MAIN POWER PANEL TO AVOID ELECTRICAL SHOCK. THE INSTALLATION MUST BE PERFORMED BY A QUALIFIED ELECTRICIAN. The thermostat’s housing is not watertight. Do NOT install the thermostat in an area where it can be exposed to water or rain. � To remove the thermostat faceplate, loosen the screw (the screw cannot be completely removed) at the bottom of the thermostat and lift the bottom of the faceplate outwards towards you. � Connect the thermostat wires to the power supply and to the load using solderless connectors for copper wires as shown below. NOTE: All wires and connections must conform to the local electrical code. This thermostat has tinned copper wires for line and load connections. Special CO/ALR solderless connectors must be used if these wires are to be connected to aluminium conductors. � Pull the temperature sensor wires through one of the openings on the thermostat base and connect the wires to terminals 1 and 2 (no polarity). • The sensor cable must not come in contact with the electrical wires and must be routed outside the electrical box and follow the wall down to the floor. • Position the sensor cable such that it does not come in contact with the floor heating wires. The sensor must be centered between two floor heating wires for best temperature control. • Do NOT staple the sensor head (the plastic end) to the floor. Doing so might damage the sensor. The damage might not be noticeable during testing but can become apparent several days later. � Push the excess length of the line voltage wires back inside the electrical box. Install the thermostat base onto the electrical box using the provided screws. � Set the DIP switches (refer to section 2.1). � Description 1. � Installation 2.
