Features
Valve control
Thermostat via built-in temperature sensor or external temperature sensor to obtain temperature, through the control valve output switching signal instructions to the room temperature is maintained at the set value.
Temperature display
Display temperature thermostat can be set according to demand internal sensor or an external sensor senses the room temperature or room temperature display settings. This can be done in the installation settings.
Timed Loop
Several times per hour frequency start valve in order to obtain a more precise temperature control room, through the timing loop (CPH) feature allows the thermostat close to the set value (temperature difference at half the bandwidth) at room temperature.
Default CPH heating mode is 4 times per hour, three times per hour in cooling mode. CPH value can be changed in the installation settings.
External temperature sensor
In addition to built-in temperature sensor thermostat, the temperature can also be controlled according to the external temperature sensor (NTC20K).
Keyboard Lock
During the installation settings, you can be set to lock the keyboard. There are four locking methods: No keyboard lock is enabled (default), the mode key lock, key lock mode and speed, all key lock
Saving mode
Or on the keys can be directly through the passive dry contact (for example, hotel room card) Operating (continuous press mode button for 3 seconds) to enter power-saving mode. If the system into power saving mode, the screen will appear. You can choose dry contacts are normally open or normally closed type set at installation.
If you are into power saving mode by dry contact, all the keys are locked, but the setting mode key combination is still valid. And if it is through the button to enter the power-saving mode, so any subsequent keystrokes will end a power-saving mode.
If the state is the heating energy-saving mode, the set value will automatically be converted to energy-saving mode setting heating temperature is usually 10 ~ 21 , the default value is 18 , can be parameterized in the installation settings, set set in steps of 0.5 .
If the state is in cooling energy-saving mode, the set value will automatically be converted to energy-saving mode of cooling set temperature is usually 22 ~ 32 , the default value is 26 , can be parameterized in the installation settings, set step length of 0.5
