Further when mounting the A4100 be aware that drafts may travel down the inside of cavity walls especially if mounted on external walls and enter the back of the thermostat or sensor enclosure through the cable entry holes in the wall It is important to fully seal these holes to prevent any drafts affecting the internally mounted temperature sensor It is recommended to mount the A4100 or remote sensors between 1 5 amp 1 7 metres from the floor where possible Move the control wires through the large opening in the thermostat base plate then place the thermostat base on the wall and using appropriate screws firmly attach the thermostat base to the wall Seal any holes where cables enter the back of the thermostat to prevent drafts entering through these holes affecting he sensor Setting the hardware switches p Switch 1 F 2 heat 2 Swi Fan Speeds Speen Pe eae Cool Heat Cool Sw3 Stages Sw4 Reversing Valve Energise in cool O If 2 ON Heat P eo iain Fan Control Fan Control by T stat Sw4 Fan Mode HG HE If Sw 2 OFF Heat cool a ga Sw5 Anti cycle timer P mmable Sw6 Operation Manual Thermostat e Thermostat Sw7 Minimum Run Sw8 Program Type Commercial Program Residential Program If Sw 6 ON Programmable Single Set point 3 Speed Fan 1 heat 1 Cool Heat Pump terminals 2 Stages Energise in heat B B Sw2 Equipment Type m b
