Fan speed ON/Off, low/med/high or auto
Auto mode, fan speed is proportional to distance of room temperature from setpoint
Manual or automatic heat / cool changeover Control of auxiliary electric heater Inbuilt or remote sensor (NTC20K) options available Simultaneous display of room temperature and user setpoint Push button adjustment of setpoint Switches allow manual control of system operation and fan speed Special energy savings mode activated by external input from Energy Management System (EMS) a window contact or hotel card-key - overrides the temperature setting to installer defined heating and cooling temperatures Energy savings input (remote setback) can be configured to be normally open (NO) circuit or normally closed (NC) circuit All models have a proportional plus integral (P+I) T6590 meets all relevant requirements for CE approval Installer setup mode allowing operating parameters to be changed Installer set up settings retained in the event of a power loss Central remote setback for both cooling and heating operation Freeze protection Automatic setback to unoccupied mode with no key operation °C display 0°C to 2°C Temperature display offset available Easy to use installer setup mode allows for simple thermostat setup Adjustable deadband for heat & cool sequence control Setpoint range 10°C to 32°C Installer test mode for on-site wiring checks Line voltage (230V~) models available
APPLICATIONS
The T6590 range of digital thermostats is designed to control the valves, fan and auxiliary electric heater within fan-coil systems. [. . . ] 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
