[. . . ] Tighten retaining screw in lower edge of thermostat. Wiring the thermostat The standard wiring access is via a hole in the centre of the thermostat wall-plate. Removing the thermostat from the wall Location The T6590 Series thermostat is the temperature control element in the fan-coil or air-conditioning system, and must be located about 1. 2 to 1. 5m above the floor (according to local building regulations) in a position with good air circulation at room temperature. Do not mount it where it could be affected by :draughts or dead spots behind doors or in corners hot or cold air from ducts radiant heat from the sun or appliances unheated (uncooled) areas such as an outside wall behind the thermostat concealed pipes or chimneys 1. 5. If it becomes necessary to remove the thermostat from the wall-plate: Isolate the power supply before removing the thermostat. Use both hands to pull the thermostat straight away from the wall-plate. NOTE - Incorrect removal of the thermostat from the wall-plate may damage the device. Any T6590 Series thermostat can be directly mounted on the wall or horizontally on either a 65x65mm standard junction box or a 2x4inch US junction box. IMPORTANT The installer must be a trained service engineer Isolate the power supply before beginning installation Mounting the thermostat 3 EN0H8579 R0 2009 T6590 FAN-COIL THERMOSTAT INSTALLER SETUP MODE (ISU) ­ T6590A1000 & T6590B1000 ISU Number and description Units 1 System Type 2 Valve output type 3 Sensor Type 5 Threshold for pipe sensor cooling 6 Threshold for pipe sensor heating 7 Fan control type ºC ºC 8 Dead band for four pipes 9 Cycles Per Hour (CPH) value for heating 10 Cycles Per Hour (CPH) value for cooling 11 Cycles Per Hour (CPH) value for Auxiliary Heater ºC 1 remote sensor (NTC20K) 0 NO input (default mode is Heat) 1 NO input (default mode is Cool) 2 NC input (default mode is Heat) 3 NC input (default mode is Cool) 4 Analog input (Default)NTC20K, T7414C1012 Range: 10-18 ºC (Default 15 ºC) Range: 24-32 ºC (Default 27 ºC) 0 User can choose Cycle or Constant (Default) (3 speed: Low->Med->High->Auto-> Low) 1 CONSTANT ONLY (3 speed: Low->Med->High-> Low) 2 CYCLE ONLY Auto has fan ramping algorithm 1ºC, 2ºC (Default), 3ºC, 4ºC, 5ºC (not available on T6590A1000) 1 ­ 12CPH (Default 4) 1 ­ 6CPH (Default 3) 1-12 (Default 6) 1 NC ON/OFF 0 Onboard Sensor (Default) 4 - 4 pipe system with manual changeover (not available on T6590A1000) 5 = 4 Pipe system auto changeover (default on T6590B1000) (Not available on T6590A1000) 6 = 2 pipe system 1H1C with Auxiliary Heater.
