Selecting use of Zone4 Damper

Dip switch #9 selects whether Damper4 is being used as

Zone4 damper or as a fresh air damper. When it is used as

a fresh air damper, the minutes per hour of fresh air is set

on the panel.

Selecting One-Zone Operation

the panel can be operated as a single (one-zone) system.

the panel will control all the dampers together based on the

Zone1 thermostat.

this can eliminate the need to change all the thermostats

when the home or building is vacant such as at night or

during vacation periods.

One-Zone operation can be selected using the 1ZnE switch

on the panel or an external switch. the LED adjacent to

the switch will be activated when One-Zone operation is

selected.

Emergency Heat Operation

Emergency Heat can be selected from Zone 1 when using

a heat pump thermostat. When using a conventional heat/

cool thermostat the Emergency Heat can be selected on

the panel switch or an external switch. If emergency heat is

activated by the panel switch or an external switch, the LED

adjacent to the switch will be lit. Any heating calls from any

thermostat will be treated as emergency heat calls.

the emergency heat switch on the panel or an external switch

cannot be used when Dip switch #4 is set to heat pump

thermostat. the emergency heat switch on the thermostat

must be used in this mode.

If an emergency heat call is initiated by a heat pump thermostat

in Zone1, an emergency heat call will occur. the panel will

treat all calls for heating as emergency heat calls until Zone1

calls for a non-emergency heat call or a cooling call.

Timer Reset Switch

Momentarily pressing the timer Reset switch clears the

built-in timers allowing the system to be checked out more

quickly.

24VAC Power

24VAC is connected to the panel at the terminals marked

24VAC. A 40VA transformer should be used and the

output connected to terminals 1 and 2 (not polarized). A

circuit breaker type fuse is located next to the terminals. If a

short should occur in the damper or thermostat wiring, the

Fuse will open the circuit and then close the circuit when the

short is removed.

WARNING! THE FuSE GETS VERY HOT WHEN

A SHORT OCCuRS AND SHOuLD NOT BE

TOuCHED.

PLEASE NOTE: YOu MuST uSE AN INDEPEN-

DENT LOW VOLTAGE POWER SuPPLY.

Heating Limit Potentiometer

this potentiometer sets the maximum Supply Air Plenum

temperature allowed in heating. A low cost Supply Air

1ZNE

Sensor can be used to monitor the temperature and if the

supply air temperature exceeds the set Heating Limit, the

EXTERNAL

SWITCH

heat is turned off and the indoor fan is activated. After two

minutes the heat will be turned back on if the supply air has

dropped below the Heating Limit.

Cooling Limit Potentiometer

this potentiometer sets the minimum Supply Air Plenum

temperature allowed in cooling. If the supply air temperature

drops below the set Cooling Limit, the cooling is turned off

and the indoor fan is activated. After two minutes the cooling

will be turned back on if the supply air has risen above the

Cooling Limit.

SWITCH

W2/W3/Y2 Timer Potentiometer

Second and third stage heating and second stage cooling

are controlled by a timer. If the panel has been calling for

heating or cooling longer than the time set on the W2/

W3/Y2 timer potentiometer, the second stage heating

or cooling will be activated provided it is not inhibited by

the Outdoor temperature Limit or the Capacity Limit. If

the panel has been calling for second stage heating longer

than the time set on the W2/W3/Y2 timer Potentiometer,

the third Stage Heating will be activated provided it is not

inhibited by a limit.
