Sleep Mode
a) The sleep mode can only be set when the unit is in cool mode or heat mode.
b) If the sleep mode is activated when the unit is in cool mode, then the indoor fan will run at low speed and Ts will
increase by 2ºC over 2 hours.
c) If the sleep mode is activated when the unit is in heat mode, then the indoor fan will run at set speed and Ts will
decrease by 2ºC over 2 hours.
d) Changing the mode of operation will cancel the sleep mode.

seconds.
Fan speed is regulated according to the profile below.
After 30 seconds the fan speed is modulated according to the difference between the room temperature and the set
temperature. The controller adjusts the motor signal input from 0 to 5VDC by PID calculation every 10 seconds. The air flow is
adjusted from 15% to100%.
Modulating Valve Control Under Energy Saving Mode
If the modulating valve is used, the water flow is adjusted from Modbus 310015 setting to 100% according to the room
temperature and set temperature. The controller adjusts the modulating valve signal input from Modbus 310015 setting to
10VDC by PID calculation every Modbus 310007 setting.
