Troom: Temperature of the room. SP: Temperature set point.
When U44 = 2:
If Troom ≥ SP + U54 in heating mode (U90 = HE),
or
if Troom ≤ SP - U55 in cooling mode (U90 = CO),
Then R2 will be energized.

Control
 Cooling Control (U90 = C0)
 Temperature control
If Troom ≥ Set-point + U22, and Te p. Output has been de-energized for U10, then Te p. Output energized;
If Troom ≤ Set-point, then Te p. Output de-energized.
 Heating Control (U90 = HE)
 Temperature control
If Troom ≤ Set-point - U22, then Te p. Output energized;
If Troom ≥ Set-point, then Te p. Output de-energized.
 Temp. Output Load Delay Protection (only for cooling control)
After power supplied, Te p. Output could be energized after U10;
After Te p. Output de-energized, it could be energized again after U10.
 Buzzer Function
Every key press, there will be a short beep. Every confir ation key press, there will be a long beep. Every error operation, there will
be three short beeps.
When there is failure, or external warning input: If U62 = 0, no buzzing warning. If U62 = 1, there will be continuous buzzing of
warning.
The waring will stop, if press〖P〗, or warning condition disappears.
 Over Temperature Warning
When Troom ≥ SP + U54, or Troom ≤ SP – U55, display warning, and buzzing
 External Warning Input
NO: nor al open. If open, no warning; if closed, warning.
NC: nor al close. If closed, no warning; if open, warning.
Locked: Warning keeps after the external warning disappeared. Press〖P〗 to stop warning.
Unlocked: Warning stops after the external warning disappeared.
Note: When there is external warning, the output(s) will be de-energized.
 Sensor Fail
R1 stop energized.
 Sensor Calibration
The sensor can be calibrated by U20.
 Restore to Factory Default Settings
Keep〖P〗and〖▲〗depressed si ultaneously for 5 sec, there will be a beep, and “UnL” displays.
Press〖▼〗twice, there will be a beep, all settings will be restored to factory default settings.

Attention
 Wiring work should be anipulated by certified technicians.
 Wrong connection could da age the controller, and the loads. Power supply to ter inal 7 and 8 to check the controller. If there is a
ulti eter, check the outputs, as well as input, by the help of settings.
 Sensor and input signal wires should not be laid together with power supply wire, and even in sa e pipe.
 Sensor wire is better as short as possible. Not wind the redundant length wire to electrical noise equip ent.
 The loads should be within the specification of the controller output driving ability. If using ac/dc odule as load, or tungsten la p,
or otor, following the below require ents to avoid surging current da aging or shorten the life ti e of the controller outputs:
For ac/dc odule as load, the rated current should be no ore 1/10th of output specification under pure resistance.
For tungsten la p as load, the rated current should be no ore 1/15th of output specification under pure resistance.
For otor, the rate current should be no ore 1/5th of output specification under pure resistance.
For exa ple: if drive a 1500W tungsten la p with 7A (pure resistance spec.) relay, the relay contactor will be burnt immediately.
 Don’t touch inside co ponents;
 Avoid installing controller in the following environ ent:
More wet than 90%RH, or easily dew; Vibrating, or will be shocked; Possible sprayed; Under erosive air; Under explosive air.
