3.2.2 Functions of the buttons
"Mode" ­ switch between "Off", "Heating", "Cooling", "Auto" settings. The display shows the current setting. If the "Mode" button is pressed for more than 10 seconds, the temperature measurement units should be changed. "Fan" ­ switch between "On", "Auto" settings. The display should show the current setting. "Fan Speed" ­ switch between "Speed 1", "Speed 2", "Speed 3" settings. The display should show the current setting. "Temperature Up" ­ increase the temperature by 0.5 °C or 1 °F per push. The display should show the current setting. The temperature should not be settings above the "maximum available temperature" value. "Temperature Down" ­ decrease the temperature by 0.5 °C or 1 °F per push. The display should show the current setting. The temperature should not be settings below 10 °C or 50 °F. New settings save to non-volatile memory after 10 seconds after the last press of any buttons.
3.2.3 The air temperature measurement
The thermostat make the air temperature measurement at least 5 times per minute and uses at least 10 last measurements for temperature averaging, i.e., every 12 seconds a new averaged temperature is calculated. The average temperature saves as the "current temperature". The accuracy of the temperature measurement is 0.25 °C.
3.2.4 The air humidity measurement
The thermostat makes the air humidity measurement at least 5 times per minute and use at least 10 last measurements for humidity averaging, i.e., every 12 seconds a new averaged humidity should be calculated. The average humidity should be saved as the "current humidity". The accuracy of the humidity measurement is 5%.
3.2.5 The CO² concentration measurement
The thermostat makes the CO2 concentration in the air measurement at least 5 times per minute and uses at least 10 last measurements for CO2 concentration in the air averaging, i.e., every 12 seconds a new averaged CO2 concentration in the air is calculated. The averaged CO2 concentration in the air should be saved as the "current CO2 concentration". The accuracy of the CO2 concentration in the air measurement is 50 ppm.

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.
