* Note: When set U24 a new value, the counter value of timer 1 will be reset to zero.Example 1: U24 = 200, the counter of timer 1 is 90, R3 or R4 status will still change 110 times. Now set U24 = 201, the counter will become 0, R3 or R4 status will change 201 times.Example 2: U24 = 200, the counter of timer 1 is now 200, R3 or R4 status will not change any more. Now set U24 = 201, the counter will become 0, R3 or R4 status wil vchange 201 times.
Control
Temperature controlCoolingIf Temp. ≥ Set-point + Hysteresis (U11), and R1 has been de-energized for protection time (U12), R1 will be energized. If Temp. ≤ Set-point, R1 will be de-energized.HeatingIf Temp. ≤ Set-point – Hysteresis (U11), and R1 has been de-energized for protection time (U12), R1 will be energized.If Temp. ≥ Set-point, R1 will be de-energized.Delay protection for R1After power supplied, R1 could be energized after protection time (U12) has passed.After R1 is de-energized, it could be energized again after protection time (U12) has passed.Timer 1, to control R3 and R4, set by U20 to U24R3/R4 switching counterThe counter counts the switching times. From the start of R3 on to next start of R3 on, it is one period, counter adds 1.If U24 = 0, R3/R4 will keep switching without stop. Else, when the counter value reaches U24, R3/R4 stops switching.Check the value of the counter: press CNT））, the value will display for 2 sec., and the Lamp Set will blink in 2Hz.Manually switching R3/R4Keep depressed for 5 sec. to switch outputs (R3 and R4) status.After switched, it will take full set time (U20 to U23) for next status switching
Multifunction R5
As timer 2 output (when U34 = 1 or 3) During the time set by U30 and U31, R5 will be energized. During the time set by U32 and U33, R5 will be de-energized.As temp. high protecting output (only in heating mode, when U34 = 2 or 3) If Temp. ≥ Set-point + U16 for U19 time, R5 will be energized. If Temp. < Set-point + U16 – U17, stop temp. high protecting
Temp. warning
When U40 = 0, no buzzing warning, only display warning code. After power supplied, the temp. warning will not be effective, until the U18 (1st Temp. warning delay time) time has passed. Temp. high warning If Temp. ≥ Set-point + U14, warning: beep, and display “Hi” and Temp. alternatively. If Temp. < Set-point + U14, stop warning. Temp. low warning If Temp. ≤ Set-point – U15, warning: beep, and display “Lo” and Temp. alternatively. If Temp. > Set-point – U15, stop warning.
Sensor
When the measured Temp. is not accurate enough, we could calibrate by setting the deviation to U13. When the sensor is not connected well, or broken, display “E1”, R1 will be de-energized. Do not install or dismount sensor under power supplied.
Buzzer Warning
When U40 = 0, there is no beeping warning, only display the warning code if any problem.When U40 = 1, there will be beeping warning, and display of warning code if any problem. Pressing any key could stop beeping.
Restore to Factory Default Settings
Keep P key and key depressed simultaneously for 3 seconds, controller displays “UnL”.Press key twice, all the settings will be restored to Fctory Set (see System parameter table).
