.4 Types of Heat Pump Installations

. Principles of Operation

The controller can be configured for either of the following types of

heat pump installations (see page 8, item 8).

.1 Automatic Heating/Cooling Changeover

•

Add-on Installation: This type of installation is performed

when adding a heat pump to an existing furnace. When the

heat pump is installed, the furnace becomes the auxiliary heat

source. In this type of installation, the indoor coils are usually

installed downstream of the auxiliary heat source. When the

controller is configured for an add-on installation, the heat

pump is disabled during auxiliary heating to prevent overpres-

sure.

New Installation: In this type of installation, as there is not

already a furnace, the auxiliary heat source is installed at the

same time as the heat pump. In this type of installation, the

indoor coils are located upstream of the auxiliary heat. When

the controller is configured for a new installation, the heat pump

and the auxiliary heat can operate simultaneously.

With automatic heating/cooling mode changeover, there’s no need

to adjust the controller at every change of season or weather condi-

tion. The controller switches automatically between heating mode

and cooling mode to maintain the desired temperature.

Manual Mode

When the controller is in manual mode, the heating/cooling mode

changeover occurs as follows:

•

The controller switches to cooling mode when the indoor tem-

perature is higher than the setpoint by more than 1.5°C (2.5°F)

for 15 minutes.

•

The controller switches the heating mode when the indoor tem-

perature is lower than the setpoint by more than 1.5°C (2.5°F)

for 15 minutes.

Automatic Mode

4.5 Interstage Delay

When the controller is in automatic mode, it follows the programmed

schedule. Two temperature settings (heating setpoint and cooling

setpoint) are programmed for each period of the schedule. The

heating/cooling mode changeover occurs as follows:

Interstage Delay is the time allocated for the temperature to return

to an acceptable value when it deviates too far from the setpoint. If

this time has elapsed, the next heating or cooling stage is activated.

The heating or cooling stage will be deactivated when the tempera-

ture returns to an acceptable value. The Interstage Delay is fixed at

•

When the controller is in heating mode, the indoor temperature

is maintained at the heating setpoint. However, if the tempera-

ture rises and remains above the cooling setpoint for 15 min-

utes, the controller will switch to cooling mode.

minutes if the controller is configured for an HVAC system and is

user-adjustable if it is configured for a heat pump (see page 8,

item 9).

•

When the controller is in cooling mode, the indoor temperature

is maintained at the cooling setpoint. However, if the tempera-

ture drops and remains below the heating setpoint for 15 min-

utes, the controller will switch to heating mode.

.6 Low and High Temperature Limits

Low Temperature Limit (LLMT) and High Temperature Limit (HLMT)

are used to keep the plenum from becoming too cold or too hot.

During cooling, if the plenum temperature is lower than LLMT, a

cooling stage is deactivated starting with the one that was last acti-

vated. If, after a while, the temperature is still too low, another cool-

ing stage is deactivated and so on. Likewise, during heating, if the

plenum temperature is higher than HLMT, a heating stage is deacti-

vated starting with the one that was last activated. If, after a while,

the temperature is still too high, another heating stage is deacti-

vated and so on. (see page 8, items 10 and 11.)

.2 Balance Points (heat pumps only)

Balance Points are used to disable the heat pump or the auxiliary

heating when the outdoor temperature is below or above a set tem-

perature.

•

When the outdoor temperature is below the Balance Point Low

bP L), the heat pump is disabled and only auxiliary heating can

(

be used (see page 8, item 5).

WARNING: LLMT and HLMT can be used in parallel with an

UL353-approved device but they do not replace such device.

NOTE: LLMT and HLMT cannot be used if the plenum temperature

sensor is not connected to the controller.

•

When the outdoor temperature is above the Balance Point High

(bP H), the auxiliary heat is disabled and only the heat pump

can be used (see page 8, item 6).

NOTE: Balance Points cannot be used if the AC144-03 outdoor

temperature sensor is not connected to the controller.

.7 Smart Fan

.3 Heating During Defrost (heat pumps only)

When Smart Fan is enabled (see page 8, item 15), the fan operates

as follows:

The auxiliary heat is activated during defrost except under the fol-

lowing conditions:

•

During periods 2 and 4 of automatic mode and during the unoc-

cupied mode (i.e., when you are away from home or sleeping),

the fan operates only when heating or cooling is activated.

The fan operates continuously the rest of the time.

•

When the outdoor temperature is above the defrost point (see

page 8, item 7). Note: This condition will not apply if the

AC144-03 outdoor sensor is not connected to the controller.

•

NOTE: For Smart Fan to work, set the fan to On (see section 5.3).

•

When the plenum temperature is above 40°C (104°F). The

auxiliary heat is re-activated when the plenum temperature

drops below 32°C (90°F). Note: This condition will not apply if

the AC146-410 plenum sensor is not connected to the control-

ler.

NOTE: The auxiliary heat’s short-cycle protection is disabled during

defrost.
