Mode Selection
- HL116DA/DA2/P: When turn on, Press “M ” to change system working in cooling “ ”, heating “ ” or ventilation “ ” mode, the related icon will flash, and a continuous switch can be performed among three models hereinbefore while “M ” key is pressed without release.
- HL116(A)FCV2: When turn on, Press “M” to change the system working in cooling “ ”, heating “ ”, Auto “ ” or ventilation
- “ ” mode in turn, the related icon will flash, and a continuous switch can be performed among four models hereinbefore while
- “ M” key is pressed without release. Thermostat auto-switch to cooling or heating mode in accordance with the result set point compared to environment temperature under AUTO “ ” mode (This mode is called AFCV2 mode).
- Fan speed selection: If the switch on the panel is slipped to position LOW、MED or HIGH, namely, the corresponding Fan speed of representation LOW、MED、HIGH symbol is selected
- Control of motorized-valve (L116DA/DA2/P）: If the difference between room temperature and set-point exceed (or under) 1℃, FCU valve will be open; if room temperature are equal to set-point, the FCU valve will close with the fan still running.
- Control cooling-heating FCU Valve under 4-pipe configuration (HL116FCV2): In cooling Mode, when the room temperature is higher than the set-point, the cooling valve will be opened. Otherwise it will be closed. Heating valve is always closed In heating, in heating Mode When the room temperature is lower than the set-point, the heating valve will be opened. Otherwise, it will be closed. Cooling valve is always closed.
LOW-TEMPERATURE PROTECTION
If the thermostat is at shut state, and when room temperature is lower than 5℃, the thermostat will start valve for heating, HL116DA/DA2/P for electric motorized valve and HL116FCV2 for heating water valve respectively, when the temperature returns to 7℃ or above, it will close valve.
SET LOW-TEMPERATURE PROTECTION
urn off the thermostat, press “ ” until the backlight is on and the parameter setting is displayed with icon “ ” and “00”, “01”, press “” or “” key to adjust. “00” indicates low-temperature protection is invalid, “01” indicates the low-temperature protection function is valid. The default is “00”.
Caution: test Mode modification is prohibited while “F” is displayed in the middle of the LCD screen
