,OCATION The Digistat SCR (receiver) should be mounted in a convenient position, close to the boiler or central heating system wiring centre. (Care should be taken not to mount the SCR in a position where it is surrounded by metal objects or mains voltage cable, as this may interfere with the radio signal). For the best performance install in an open space, at least 30cm distance from any metal objects including wall boxes and boiler housing.

. Take the Digistat RF and hold it within sight of the SCR (no closer than one metre). 6. Remove the battery cover and fit the batteries. 7. The Digistat RF should now display the actual room temperature. If the unit has been stored in a cold place, it may take time to warm up. 8. As soon as the batteries are fitted, the red LED on the SCR should flash for 7 seconds and then go out. The green LED may be on or off depending on the room temperature at the time of commissioning. 9.

,OCATION Room Thermostat 1.5 m Care should be taken to mount the thermostat in a position which is not subject to direct sunlight or draughts. Preferably it should be mounted on an inside wall about 1.5m (5ft) above the floor in a position where it can respond to room temperature but away from the direct influence of radiators or other appliances giving off heat. 3IGNAL 3TRENGTH 2& -ODELS Before fixing the Digistat+RF to the wall it is recommended to first check the signal strength from that location.
