Page 7: Control Modes
GENERAL DESCRIPTION Control modes The timed thermostat can be set with 2 different control modes: • Master: the timed thermostat sets the type, operating mode or setpoint of the devices configured as Slaves (e.g. the Easy flush-mounting thermostats GW1x765H). In the first case (mode), the thermostats use the setpoints set locally. -

This parameter is only visible if the back- lighting is active. If the type of management is MAN, use button key to choose the required percentage of light intensity (the gap can be set from 30 to 100%).
- Page 18 USER INSTRUCTIONS Setting the alarm threshold temperature Use the button key to set the maximum floor-level temperature above which the timed thermostat suspends heating to prevent any possible damage (the value is expressed as tenths of °C, and can be set from 150 to 1000 in steps of 100). This parameter is only visible if the NTC temperature probe sensor connected to the timed thermostat has been enabled as a temperature probe (TEMP).

- Page 24 USER INSTRUCTIONS Temperature adjustment control algorithm Use the button key to modify the control algorithm for heating , cooling , or both (2P = two points ON/OFF; PI = PWM proportional-integral; FAN = fan coil with speed control ON/OFF) depending on the type of operation and the control logic set on the previous screens.
- Page 25 USER INSTRUCTIONS Setting the adjustment differential Use the button keys to set the value of the adjustment differential of the two-point control algorithm (the gap can be set from 0.1°C to 2.0°C). To confirm your choice and move on to the next parameter, press the button key within 30 seconds.
- Page 26 USER INSTRUCTIONS PWM PROPORTIONAL-INTEGRAL The PWM control algorithm, used to control the temperature adjustment system, allows you to drastically reduce the times subject to thermal inertia and introduced by the two- point control. This type of control involves the modulation of the impulse duty-cycle, represented by the temperature adjustment system activation time, on the basis of the difference between the fixed setpoint and the temperature effectively detected.
- Page 27 USER INSTRUCTIONS The device keeps the temperature adjustment system switched on for a cycle time percentage that depends on the output function of the proportional-integral control; the device continually adjusts the system, modulating the system ON-OFF times with a duty- cycle that depends on the value of the output function (calculated at each time gap equal to the cycle time).
- Page 28 USER INSTRUCTIONS FAN COIL WITH ON-OFF SPEED CONTROL The operating principle involves activating/deactivating the fan coil speeds on the basis of the difference between the fixed setpoint and the detected temperature, using independent 1-bit communication objects to manage the individual speeds. The figures below refer to the control of the speeds of a fan coil with three operating stages for heating and cooling.
- Page 29 USER INSTRUCTIONS Speed V1 is activated when the temperature value is lower than the “setpoint - valve ” value (in heating mode) or higher than the “setpoint + ” value 1heat valve 1cond (in cooling mode), and deactivated when the temperature value reaches the “setpoint - ”...
- Page 30 USER INSTRUCTIONS Setting the adjustment differential for speed 1 Use the button key to set the value of the adjustment differential of fan coil speed 1 (the gap can be set from 0°C to 2.0°C). If a value of 0°C is set, then when the solenoid valve is activated fan coil speed 1 will be activated as well.

Page 38: F.a.q
USER INSTRUCTIONS F.A.Q. What does the temperature value on the display actually represent? If no external temperature probe is enabled during programming, the value shown on the display is the temperature detected by the sensor in the timed thermostat. If, however, an external temperature probe (of the Easy or NTC type) has been enabled, the timed thermostat shows the average of the values detected by the probe and the sensor, using a variable weight between 10% and 100% (which can be defined via Easy configurator). - Page 39 USER INSTRUCTIONS F.A.Q. What happens to the time band set on the timed thermostat if the BUS power supply fails and is reset? If the device is fitted with batteries, the time and date are maintained until the battery charge runs out. Is it possible to understand whether the potential-free contact input is open or closed? The timed thermostat display shows whether the contact is closed...
