Operation

Sequence of Operation

Automatic 3-minute

Compressor Lockout

After the compressor cycles off, it will not restart for three minutes. This feature prevents the compressor from short cycling and extends the overall life.

Automatic 2nd Stage Electric Heat (PTHE only)

If the room temperature falls to 2.5°F below the setpoint temperature or the unit compressor fails, the reverse cycle heat is shut off and the electric heat is turned on.

Indoor Room Freeze

Protection

When the unit senses room temperatures of 40°F or below, the unit activates the indoor fan motor and either the electric resistance heater or the hydronic heater to help prevent pipes or fixtures from freezing.

This also overrides the Energy Management System input for unit mounted or wall mounted display modules

Random Restart Function

This function allows random restart of the PTAC units in the event of a power outage. The restart delay reduces the initial inrush current from the building to help prevent a second power outage caused by too much current draw.

The random restart function will occur after every power up cycle by delaying the operation of the unit for 0 to 90 seconds. Compressor minimum off time is enforced after the random restart function has completed.

Door Switch Occupancy Sensor

The PTAC can accommodate a field- installed door switch and occupancy sensor to operate the energy management feature.

Remote Thermostat Control

Each unit can be operated from any standard 4 or 5-wire, remote- mounted thermostat. Also, the unit has a built-in low voltage power source that can accommodate either a manual, auto changeover, or programmable thermostat.

Setpoint Limiting

The setpoint limiting feature reduces energy costs by controlling the maximum setpoint in heating and the minimum setpoint in cooling.

Active Defrost (PTHEs only)

PTACs have an active defrost system that removes ice build-up on the outdoor coil, which may occur during the heat pump cycle.

Remote Thermostat

Operation

The GL, GH, O, W, Y, R, and C terminals provide control inputs for a remote wall-mounted thermostat.

The terminals listed control the operation of the unit when no display module is used. A display module will take precedence over any of these inputs.

Mode Button Operation

OFF - cooling and heating functions stop.

HEAT - room temperature is maintained by cycling in heat pump mode or electric heat. The model PTHE switches from heat pump mode to electric heat when the outdoor air temperature is below 20°F (approximately), or when the heat pump cannot keep up with the heating load when using a two-stage thermostat.

COOL - room temperature is maintained by cycling the air conditioner.

FAN - the fan runs at the user selected speed or runs as otherwise configured.

Fan Mode

Fan Operation

The fan speed may be user selected as either high or low. Fan cycling versus continuous is operation configurable. See section on configuration for details.

Front Desk Control (FD1, FD2 Inputs)

The energy management input is used to move the setpoint up in the case of cooling and down in the case of heating. This conserves energy by reducing the demand in the space.

The energy management input is a dry contact closure; typically this is driven from either a occupancy sensor or a front desk control system.
