the thermostat through built-in temperature sensor or external temperature sensors for temperature, through the control valve switch signal output instruction to
the room temperature at a set value.
display the temperature hvac thermostat can be set according to the requirements for the built-in sensors or external sensors to room temperature, or
display the room temperature set point. This can be done in the installation Settings.
in order to obtain more accurate temperature control room, through the timing cycle ( CPBD function can make the thermostat at room temperature is close to a
value ( Temperature difference in half the bandwidth) When several times per hour frequency start valve.
the CFH's default value is heating mode 4 times per hour, the refrigeration mode 3 times per hour. CPH value can be set during the installation in
an external temperature sensor
in addition to the temperature of the thermostat built-in sensors, can also according to an external temperature sensor TC20K) For temperature control.
in the installation Settings, can be set for keyboard lock. There are four mechanisms: is not enabled keyboard lock ( The default) ,
type key lock, patterns, and wind speed key lock, all key lock
energy saving mode
by passive dry contact ( For example, the hotel room card) Or directly to manipulate (the keys Continuous press mode key 3
seconds) Into energy saving mode. If the system into energy saving mode, the screen will appear. Can choose dry when installation Settings
contact is normally open or normally closed.
if it is through the dry contact into energy saving mode, so all keys will be locked, but key combination to enter setup mode is
effective. If is through the button into energy saving mode, then any buttons will knot east energy saving mode.
if in a heating state energy saving mode, the set value will automatically be converted to energy saving mode of heat setting temperature, usually of 10 ℃
21 ℃. The default value is 18 ℃, can to set parameters in the installation Settings, setting step for the Q. 5C。 Energy saving mode if
in the refrigeration condition, the set value will be automatically converted into energy saving mode of refrigeration set temperature, usually in the form of 22 ℃
32 c, the default value is 26 ℃, can undertake parameter setting in the setup, setting step for the a5 ℃
