A Manual Version 0.2 6 Mesh Network Thermostat and Gateway Manual 4.4 Thermostat - Control outputs When any of the "W", "W2", "AUX" outputs are on the PWM control, the output should be switched to ON state at the start of the PWM period and should be switched to OFF state at the end of the PWM duty cycle or when the "current temperature" is great than or equal to the "setpoint temperature". If the "current temperature" is greater than or equal to the "setpoint temperature" at the start of the PWM period, the PWM duty cycle length should be equal to 0 seconds, i.e., the output should not be switched to ON state during this PWM period. The real PWM duty cycle length should be stored in the "Last actual PWM duty cycle length" parameter. "When any of the "Y", "Y2" outputs are on the PWM control, the output should be switched to ON state at the start of the PWM period and should be switched to OFF state at the end of the PWM duty cycle or when the "current temperature" is less than or equal or equal to the "setpoint temperature". If the "current temperature" is less than or equal to the "setpoint temperature" at the start of the PWM period, the PWM duty cycle length should be equal to 0 seconds, i.e., the output should not be switched to ON state during this PWM period. The real PWM duty cycle length should be stored in the "Last actual PWM duty cycle length" parameter. In the "System" state each output is controlled by two bits in the control word. Two bits in the control word: 0 output is in OFF state. 1 output is in ON state. 4.5 Thermostat - State list Table 5 State list State Function Control O/B Heat Pump NO Heat Pump - YES Control W Heating stage 1 ON Control W2 Heating stage 2 ON Control AUX Heating stage 3 ON Control Y Cooling stage 1 ON Control Y2 Cooling stage 2 ON Impact Manual Version 0.2 7 Mesh Network Thermostat and Gateway Manual 4.6 Thermostat UI operations Table 6 UI operations State Function Main screen state machine Monitoring - Current temperature - Target temperature - Temperature unit - Humidity - Time - Room number - Fan mode - Fan speed - Mode Increment target temperature The main screen is displayed 1.
