Performex-1TM CONTROLLER : OPERATION & FUNCTIONS
TheZamil Packaged units areprovided with technologically advancednewPerformexTM Controller Microprocessor Based Electronic
Control Board, incorporating the following benefits and features:
- COMPLETE UNIT CONTROL: Provides complete unit control for heating and cooling application whether single
stage or two stage utilizing the input from sensor that measure temperatures during unit operation.
- COMPRESSOR LOCKOUT: If any of the unit’s safety controls trip due to abnormal conditions the Electronic Control
locks out the compressor, preventing restart, unless attended by qualified service technicians. The unit can be re-
started only by reset the thermostat after ensuring safe system conditions.
- LEAD LAG OPERATION: The unit electronic controls automatically alternate lead and lag the compressors for even
operation. Compressor #1 can be set always lead as an option.
- ANTI-RECYCLE TIMER: For compressor safety in case of accidental manual reset or immediate recycling of
thermostat due to load demand. This considerably improves compressor life.
- PUMP DOWN OPTION: In units equipped with pump down system the time delay creates the required time gap be-
tween the solenoid opening and compressor start to equalize the pressure in the system prior to compressor start up.
- AUTO/MANUAL RESET OF THE ALARM SIGNALS.
- FULL CONTROL OF THE INDOOR FAN: Fan operation can be selected either to run continuously or stage with the
compressor/heaters.
-PROTECTION: The PerformexTM Controller will provide the following protection:
1. Compressor high pressure protection (option)
2. Compressor low pressure protection
ELECTRONIC THERMOSTAT
LCD display: a) Room temperature display
b) Mode of operation (Cool/Heat/Auto/Fan system control)
c) Set temperature
d) Compressor Status - ON/OFF/FAULT
e) Error Codes
1. ON/OFF: Press the ON/OFF button & the unit shall be switched ON. A status Led adjacent to this button shall light up
indicating the unit is switched ON. To shut off the unit, press this button again.
2. MODE: Press the mode button to select the desired mode. On selection the corresponding icon shall be displayed on
the LCD display panel.
3. TEMPERATURE RANGE AND SETTING: The operating temperature range is 160C to 300C (610F to 860F), both
inclusive. Press the UP or DN button to select the desired temperature. The temperature setting is effective only for
the Cool, Heat and Auto modes.
4. INDOOR (EVAPORATOR) FAN: Thereis one indoorfanwith single fanspeed. When fanspeedon LCDpanelis HIGH,
indoor fan will always turns on. Indoor fan can be set off, when the compressor is cut off by setting the fan speed to
AUTO on the LCD panel by pressing Fan button. By pressing the Fan button again the fan speed can resume to HIGH.
5. COOL MODE: Whenever the unit is started in cool mode (without Pump Down Solenoid-PDS), the compressors will
be turned on one by one depending on the load requirement of the unit.
6. HEAT MODE (HEATER MODEL): Whenever the unit is started in heat mode, the heaters shall be switched ON one
by one to meet the load requirement.

7. LEAD/LAG OPERATION: Whenever a compressor needs to be on, the controller will turn on the compressor with the
shorter accumulated run time provided its 3 minutes minimum off time has lapsed. Otherwise the other compressor will
on first. Similarly, the compressor with the longer accumulated run time will be the first one to be cut off. This is to load
the compressors evenly over long run period. Balance loading is enabled when compressor #1 lead option is disabled.
8. AUTO MODE: In Auto mode, operating mode will be selected automatically between Heat and Cool mode, depending
on the Room Temperature and Set Temperature.
9. ERROR CODE:
Error code is displayed on the LCD panel. When system on and error code is shown, the ON/OFF LED on the LCD
panel will blink. When system off, error code is still display for thermistor error but the ON/OFF LED will be off.
E06 Compressor 1 high pressure trip (or contact open)
E07 Compressor 2 high pressure trip (or contact open), (not applicable for single compressor units)
E10 Compressor 1 low pressure trip
E11 Compressor 2 low pressure trip, (not applicable for single compressor units)
CRANKCASE HEATER
The crankcase heater is provided to hold the compressor oil reservoir at higher temperature than the coldest part in the
system.
•Power must be supplied to crankcase heater for a minimum of 12-hours prior to system start-up. If power is off for 6-
hours or more, crankcase heater must be energized for 12-hours before operating the system. Otherwise compressor
damage may result.
PUMP DOWN CONTROL
If the unit is provided with pumpdown system, then a solenoid type valve is installed in the liquid line ahead of expansion
valve to prevent flow of refrigerant into the evaporator during off cycle. The controller is wired to solenoid valve which
energize in cooling and opening the valve. Whenever the thermostat temperature is satisfied, the solenoid will close
followed compressor off after pumping the refrigerant from low side of the system until the low pressure switch open the
control circuit.
