MODEL DENOMINATIONS
HL116
DA/DA2: C ontrol Motorized Valve (DA: Control 2-wire N.C. FCU valve; DA2: Control 3-wire FCU valve) and
3-speed fan; When the temperature reaches the set-point, it will close the Motorized Valve with the
fan still running.
(A)FCV2: Control 4 pipe fan coil units, Control two Motorized Valv es and 3-spee d fan, when the temperatur e
reaches the set-point, it will close the Motorized Valves with the fan still running.
P: Control 3-wire FCU valve (Floating Arithmetic) and 3-speed fan; when the temperature reaches the
set-point, it will close the Motorized Valve with the fan still running.

" Control of motorized-valve （HL116DA/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 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 set-point, the heating valve will be opened.
Otherwise it will be closed. Cooling valve is always closed.
LOW TEMPERATURE PROTECTION
" If thermostat is at shut state, and when room temperature is lower than 5℃, thermostat will start valve for heating,
HL116DA/DA2/P for electric motorized valve and HL116FCV2 for heating water valve respectively, when temperature
returns to 7℃ or above, it will close valve.
SET LOW TEMPERATURE PROTECTION
"Turn off the thermostat, press “ ” until backlight is on and parameter setting is displayed with icon “ ” and “00”, “01”,
press “S” or “T” key to adjust. “00” indicates low temperature protection is invalid, “01” indicates low temperature protection
function valid. The default is “00”.
Caution: test Mode modification is prohibited while “F” is displayed in the middle of the LCD screen.
