Description

 

 

 

 

DX

44

2284, 2286,

The actual status of the DX cooling compressor.

 

 

2287

 

DO 5

45

2287, 2299

Digital output 5 controls a 24 Vac load with an ON or OFF

 

 

 

status.

EHEAT 1

45

2281, 2283,

The actual status of the first stage of electric heat.

 

 

2284, 2286

 

 

 

 

 

DO 6

46

2287, 2299

Digital output 6 controls a 24 Vac load with an ON or OFF

 

 

 

status.

EHEA T 2

46

2281, 2283,

The actual status of the second stage of electric heat.

 

 

2284, 2286

 

 

 

 

 

DO 7

47

2287, 2299

Digital output 7 controls a 24 Vac load with an ON or OFF

 

 

 

status.

EHEAT 3

47

2281, 2283,

The actual status of the third stage of electric heat.

 

 

2284, 2286

 

 

 

 

 

DO 8

50

2299

Digital output 8 controls a 24 Vac load with an ON or OFF

 

 

 

status.

FAN

50

2281, 2283,

This point is a digital output used to control the fan. ON

 

 

2284, 2286,

indicates that the DO is energized; OFF indicates that the DO is

 

 

2287

de-energized.

 

 

 

 

NGT HW HTG

53

2281, 2283,

YES indicates that the heating valve will be kept open in night

 

 

2284, 2286,

mode in both heating and cooling modes (recommended for

 

 

2287

systems with hot water). NO indicates heating valve will be

 

 

 

controlled normally.

 

 

 

Valid input: YES or NO

 

 

 

 

NGT CLG MODE

54

2281, 2283,

YES indicates that night cooling is available. NO indicates that

 

 

2284, 2286,

night cooling is not available.

 

 

2287

Valid input: YES or NO

 

 

 

 

AUX OUTPUT

55

2281, 2283,

Indicates the percentage of time the auxiliary radiation will be

 

 

2284, 2286

ON.

 

 

 

Valid values: 0 to 100%

 

 

 

 

AUX HTG TIME

57

2281, 2283,

The period of the auxiliary radiation pulse-width modulation

 

 

2284, 2286

algorithm.

 

 

 

Valid values: 0 to 255 minutes

 

 

 

 

EHT STG DELY

58

2281, 2283,

Delay between a stage of electric heat changing state and the

 

 

2284, 2286

next change of state of any stage.

 

 

 

Valid input: 0 to 255 seconds

 

 

 

 

DO DIR.REV

59

2281, 2283,

The configuration setup code for DOs. Allows the DOs to be

 

 

2284, 2286,

direct or reverse acting (enabled equals energized or enabled

 

 

2287, 2299,

equals de-energized).

 

 

 

 

HTG OUTPUT

60

2281, 2283,

If the heating control device is a valve or face-bypass damper,

 

 

2284, 2286,

then the value of this point indicates the position of the heating

 

 

2287

actuator. If electric heat is used, then the value of this point

 

 

 

determines how many stages are ON.

 

 

 

Valid values: 0 to 100%
