Pelonis PP12HMB82 12,000 BTU 230-Volt Packaged Terminal Air Conditioner

AIR CONDITIONER FEATURES

This unit has many features. The servicer must be familiar with these features in order to properly service the unit.

Compressor Restart Delay

This feature extends the overall life of the compressor by preventing the shorting cycling of the air conditioner. When the compressor restarts, the unit is designed to give a minimum of three minutes to have a time of equalizing the refrigerant pressures for optimizing cycling.

Memory

The unit has memory. If power is lost, all of the control settings (mode, fan speed, on/off and configuration) are remembered. So when power is restored, the unit will start back up in the mode (and configuration) it was in, before power was lost.

Automatic Evaporator Freeze Protection

Automatically keeps the evaporator from freezing, the compressor is turned off and the indoor fan is turned on when the evaporator temperature is too low. If the evaporator temperature is not too low this function is off.

Automatic Quick Warm-up (for heat pump models only)

If the room temperature falls to 4.5°C/8°F below the set point temperature, the reverse cycle heat is shut off and the electric strip heat is turned on for one cycle, until the set temperature is satisfied.

LED Indicators and Buttons

The touch pad has buttons for MODE,FAN, POWER, SETPOINT UP and SETPOINT DOWN. It also has LEDs that correspond to the mode, fan speed, power, and set point operation to indicate the unit status. LEDs for HIGH, MED and LOW indicate the fan speed that is selected. LEDs for FAN, COOL and HEAT indicate what operating mode is active. LED for POWER is the unit ON/OFF status LED. If the unit is in ON mode, the LED will be green. If the unit is OFF, the LED will be off.

High Temperature Protection In Heating Operation

The compressor and (or) electric heater will be switched off to prevent damage in high indoor blow air temperature or error indoor temperature sensor.

Temperature Display Configuration(°F or °C)

The unit can display in either °F or °C.

CONTROL PANEL OPERATION

The control panel keypad will look like the following Fig. 1. For some models with REMOTE SIGNAL RECEPTOR, the unit can be controlled by the control panel alone or by the remote.

POWER

Press the POWER button to turn the unit on or off. When the unit is on, the power indicator light will be green. When the unit is off, the light will go out.

MODE

Push this button to cycle through the modes from COOL-HEAT-FAN-COOL.The indicator light beside the “MODE” option will illuminate, identifying the mode selected.

• COOL: The range of set temperature is 62°F-86°F (17°C-30°C). Cooling begins automatically when the room temperature is above the set point,and stops when the room temperature is 4°F (2°C) below the set point. But the compressor will run 5 minutes at least in COOL mode before stopping. The fan runs in continuous mode.
• HEAT: The range of set temperature is 62°F-84°F (17°C-29°C). For heat pump models, the unit can alternate to run between the reverse cycle heat mode and electric mode according to the difference between the setting temperature and the room temperature. The fan motor cycles on and off with the compressor and electric heater.
• FAN: Fan operation only without heating and cooling.

NOTES

The reverse cycle and electric heater cannot be ran at the same time. In following cases, it is normal that the reverse cycle does not operate.

1. When the outdoor temperatrue is lower than 4°C/40°F or the room temperature falls to 4.5°C/8°F below the set point temperature.
2. There is a 3-minute minimum compressor run time at any setting to prevent short cycling.The indoor fan motors starts before the compressor and stops after the compressor cycles off.
3. Push the S1 on the DIP SWITCHES to UP (ON) position.
4. When frost builds up to the evaporator coils, the unit will defrost automatically and the compressor will cycle off.

UP/DOWN BUTTONS ( + / - )

Push the UP (or DOWN) button to increase (or decrease) the set temperature of the unit in cooling or heating mode. The temperature can be set by increments of 1° F (1°C). The setting temperature appears in the display.

FAN (FAN SPEED)

WALL THERMOSTAT TERMINAL (Optional)

Thermostat Wire Routing

Thermostat wire is field supplied. Recommended wire gauge is 18 to 20 gauge solid thermostat wire.

NOTE It is recommended that extra wires are run to unit in case any are damaged during installation. Thermostat wire should always be routed around or under, NEVER through, the wall sleeve. The wire should then be routed behind the front panel to the easily accessible terminal connector

Wired Wall Thermostat Connection Instructions

Remove the two screws as shown below and take the cover panel down to enable wall thermostat

NOTES

• Use terminal 4-way for heat pump connection only.
• Suggest to set the compressor protection time more than 3 minutes in the wall thermostat. If set less than 3 minutes, the compressor will still delay start by 3 minutes.
• Wall thermostat must have a 4-way valve output.
• For thermostats that have only one fan speed output (on or auto), the fan speed is determined by how the terminal connector is wired. If Low fan is desired, wire the G output from the thermostat to (LOW-FAN) on the units terminal block. If High fan is desired, wire the G output from the thermostat to (HI-FAN) on the units terminal block.
• The range of set temperature of the wall thermostat must be in the allowable range of the DIP switch setting.
• The wall thermostat must also have the correct unit type setting: heat pump or no heat pump.
• If the wall thermostat has only one electrical heater output, connect the two terminals of HEAT 1 and HEAT 2 together to form one terminal and then connect. Otherwise, connect both HEAT 1 and HEAT 2 terminals to the wall thermostat heater outputs.
• Please do not remove the control panel.

FRONT DESK CONTROL

The controller can handle a switch signal from FC (L) and FC (N) input, called front desk control. Input must be 24VAC. If system doesn’t receive a 24VAC signal, it will turn the unit off; otherwise, the unit runs in normal control.

• The DIP switch can control the FRONT DESK CONTROL feature. The DIP switch is on the DOWN position, the unit will be turn off; otherwise, the unit runs in normal control. See Fig B.
