6. Control Function
6.1 Cooling Control
If Troom ≥ Set-point + U22, and Temp._output has stopped for U10, then Temp._output energized;
If Troom ≤ Set-point, and Temp._output has run for U11, then Temp._output de-energized.
Temp._output forced energized
When not defrosting, keep〖▼〗depressed for 5 seconds can force Temp._output energized for 30 min.
During forced cooling, keep〖▼〗depressed for 5 seconds will stop forced cooling.
6.2 Heating Control
If Troom ≤ Set-point - U22, and Temp._output has stopped for U10, then Temp._output energized;
If Troom ≥ Set-point, and Temp._output has run for U11, then Temp._output de-energized.
Temp._output forced energized
When not in setting status, and Temp._output de-energied, keep〖▼〗depressed for 5 seconds can
force Temp._output energized.
During forced heating, keep〖▼〗depressed for 5 seconds will stop heating.
6.3 Temp._output delay protection
After power supply, Temp._output could be energized after U10;
After Temp._output de-energized, it could be energized again after U10;
After Temp._output energized, it could be de-energized after U11.

6.4 Fan Control Mode (for ZL-630A)
*. U43 = 0: Controlled Mode
When cooling, if Tpipe < U40, and Temp._output has run for U41, fan energized;
If U41 = 0, fan will be energized right after the Temp._output energized.
After Temp._output has de-energized for U42, fan de-energized.
If U42 = 0, fan will be de-energized right after the Temp._output de-energized.
*. U43 = 1: Fan stops during defrosting. At other time, fan works as following
In cooling mode, during Temp._output de-energized:
If U44≠0 and U45≠0: fan runs for U44, stops for U45, repeatedly, till Temp._output energized;
If U44≠0 and U45 = 0: fan keeps running;
If U44 = 0: fan keeps stopping.
*. U43 = 2: Fan stops during defrosting. At other time, fan keeps running
*. U43 = 3: Fan runs during defrosting. At other time, fan works as following
In cooling mode, during Temp._output de-energized:
If U44≠0 and U45≠0: fan runs for U44, stops for U45, repeatedly, till Temp._output energized;
If U44≠0 and U45 = 0: fan keeps running;
If U44 = 0: fan keeps stopping.
*. U43 = 4: Fan runs during defrosting. At other time, fan keeps running also
6.5 Protecting Run When Room Sensor Fails (for Cooling Mode)
When room sensor fails, Temp._output will be energized and de-energized periodically.
For every 30 minutes, Temp._output will be energized for Trun = U12 * 3 minutes, de-energized for (30
-Trun) minutes.
If U12 = 0, no protecting run.
6.6 Run When Pipe Sensor Fails
When pipe sensor fails, the defrost function will be canceled (for ZL-620A and ZL-630A).
When pipe sensor fails, and the fan works in controlled mode, fan will be only works according to U41
and U42 (for ZL-630A).
6.7 Defrost (for Cooling Mode)
Defrost Start: After Temp._output energized for U30, and Tpipe < U32, defrost starts.
Defrost End: When Tpipe > U32, or the defrosting has lasted for U31, defrost ends.
Note: for ZL-610A, only acts according to U30 and U31.
Electrical Defrost (U38 = 0): during defrost, Temp._output de-energized, defrost relay energized.
Gas or Pump Defrost (U38 = 1): during defrost, Temp._output energized, defrost relay energized.
Manually Forced Defrost:
During none-defrost status, keeping〖▲〗depressed for 7 seconds will start forced defrost;
During defrost status, keeping〖▲〗depressed for 7 seconds will stop forced defrost;

Dripping Water: after defrost finished, the device will be dripping for U33, then start cooling again.
Note: No dripping function: when the manual forced defrost finished, or when the pipe sensor fails.
Check for Tpipe, Left Time of Defrosting, Left Time of Dripping Water:
When Troom displayed, press〖▲〗will show Tpipe. ZL-610A does not have this function
Attention: when this key is depressed for 7 seconds, it will start forced defrost.
When defrosting, press〖▼〗will show the left time of defrost.
When dripping, press〖▼〗will show the left time of dripping.
7. Buzzer
Every press of key, there will be a short beep. Every confirmation press, there will be a long beep.
Every error operation, there will be three short beeps.
When the device has failure, or external warning input:
If U62 = 0, no buzzing warning.
If U62 = 1, there will be continuous buzzing for warning.
Press〖P〗can stop warning, if warning condition disappears.
8. Over Temp. Warning
When Troom ≥ Set-point + U50, there will be warning if the following condition meets:
U50 > 0 (U50 is not set to 0):
If power just supplied, U53 has passed;
If defrost just finished, U34 has passed;
The Troom keeps up condition for U52.
When Troom ≤Set-point –U51, there will be warning if the following condition meets:
U51 > 0 (U50 is not set to 0):
If power just supplied, U53 has passed;
If defrost just finished, U34 has passed;
The Troom keeps up condition for U52.
9. External Warning Input
NO: normal open. If open, no warning; if closed, warning.
NC: normal 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 outputs de-energized.
10. Sensor Calibration
The room sensor and pipe sensor can be calibrated by U20 and U21.
11. Restore To Factory Default Settings
Keep〖P〗and〖▲〗depressed simultaneously for 5 sec, there will be a short beep, and “UnL” displays.
Press〖▼〗twice, there will be a beep, all setting will be restored to factory default settings.`
