Control

On/offline:

On/off can be set by remote controller.

If set by “AUTO” key on the panel, the working mode is auto mode, fan speed is auto speed, temperature set-point is 24℃.

 

Working mode:

Set working mode by remote controller: switch between

auto -> cool -> dry -> heat -> ventilation.

Dry mode is same as cool mode with low fan speed.

 

Auto Working mode:

After power just supplied, controller will judge the working mode.

If the Troom ≥ SP + 3℃, work in cooling mode.

Else if the Troom ≤ SP - 3℃, work in heating mode.

Else work in ventilation mode.

After the working mode judged, even the Troom goes very high or very low, the working mode will keep.

*. SP: temperature set point

*. Troom: temperature of the room

 

Cool Working mode:

Auto fan speed:

If Troom ≤ (SP + 2℃), low fan speed

If (SP + 2℃) < Troom ≤ (SP + 4℃), medium fan speed

If Troom > (SP + 4℃), high fan speed

Every time the fan speed switched, it will keep at least 10 seconds.

Valve and fan:

If Troom ≥ (SP + 1℃), valve and fan are energized.

If Troom ≤ (SP - 1℃), valve and fan are de-energized.

Every time the valve and fan are switched between energized and de-energized, it will keep at least 10 seconds.

 

Heat Working mode:

Auto fan speed:

If Troom ≥ (SP - 2℃), low fan speed

If (SP - 2℃) > Troom ≥ (SP - 4℃), medium fan speed

If Troom < (SP - 4℃), high fan speed

Every time the fan speed switched, it will keep at least 10 seconds.

Valve and fan:

If Troom ≤ (SP - 1℃), valve and fan are energized.

If Troom ≥ (SP + 1℃), valve and fan are de-energized.

Every time the valve and fan are switched between energized and de-energized, it will keep at least 10 seconds.

 

Ventilation Working mode:

In this mode, there is no auto fan speed, and the fan speed can be switched at any moment.

 

Low Temperature Protection:

During offline, when Troom ≤ 5℃, the controller will run in heat working mode with high fan speed.

This working mode keeps, until the Troom ≥ 7℃, the controller will stop heating.

During this protection heating, the “POWER” LED will blink.

 

Sensor Failure:

When sensor fails, the “RUN” LED will blink, all outputs are de-energized.

 

Timer:

Timer on/off is set by remote controller.

Press remote “Timer” key to switch between timer on, timer off, without timer.

Press up/down key to set the time of timer, from 1 to 16 hours.

When timer is set, the yellow “TIMER” LED is on.

On/off operation will clear the timer set, and the “TIMER” LED will be off.
