TECHNICAL SPECIFICATIONS:
SYSTEM SUPPLY :
230 VAC +/- 15%
OUTPUT CONTACT RATING :
Output contact rating for AC 25 A at 230 VAC
INDICATIONS:
- Healthy: Indicates controller is working healthy.
- ALARM: when this LED glows it indicates som e fault is present.
- AC1 ON: when this LED glows it shows AC is ON
WORKING:
In normal working conditions when power is tu rned ON, after Power On Delay (10 Sec) AC will be turned O N. Display will show supply voltage, & room temperature. A/C indication will be ON indicating that A/C is running.
In this condition system makes ON/OFF of A/C depending on the set point of temperature during On Time set & remains OFF for the duration of Off Time set. Hyste resis for room temperature is settable. This is normal running c ondition of the system. If fault occurs to one A/C then it is tu rned OFF. To view/change set points of over voltage, u nder voltage, temperature, hysteresis of temperature, press FUN key and put password 15.
NOTE: To use DEC Key user can hold display.
RUNMODE Display:
“t” — Temperature
“v” — Voltage
“OVF” — Over Voltag e fault
“UVF” — Under Volta ge fault
“rHF”— Room High f ault
“rLF” — Room Low fault
“tSF” — Room Temp Sensor fail fault
“tin” — Timer remaining for AC Status change
NOTE: To use DEC Key user can hold display.
PARAMETER SETTINGS: Password is 15.
