HTG LOOPOUT

{80}

2583, 2584

Heating temperature control loop output value in percent.

 

 

 

 

ELEC HEAT ON

81

2584

Value, in percent, that the heating Ioopout must exceed for

 

 

 

the electric heat to turn ON.

EHEAT 1 ON

81

2583

Value, in percent, that the heating loopout must exceed for

 

 

 

the first stage of electric heat to turn ON.

 

 

 

 

CMP1 ON

82

2583

Value, in percent, that the active temperature control

 

 

 

loop output must exceed for compressor 1 to turn ON.

 

 

 

Actual turn on is subject to the CMP MlN OFF time being

 

 

 

expired. lt is also the value, in percent, which HTG

 

 

 

LOOPOUT must go below for the electric heat (ELEC HEAT

 

 

 

1) to turn OFF when only one compressor is used.

HTG CMP1 ON

82

2584

Value, in percent, that the heating temperature control loop

 

 

 

output must exceed for heating compressor 1 to turn ON.

 

 

 

Actual turn on is subject to the HTG1 MlN OFF time being

 

 

 

expired.

 

 

 

 

CMP1 OFF

83

2583

Value, in percent, that the active temperature control loop

 

 

 

output must go below for compressor 1 to turn OFF. Actual

 

 

 

turn off is subject to the CMP1 MlN ON time being expired.

HTG CMP1 OFF

83

2584

Value, in percent, that the heating temperature control loop

 

 

 

output must go below for heating compressor 1 to turn OFF.

 

 

 

Actual turn off is subject to the HTG1 MlN ON time being

 

 

 

expired.

RVAL SWITCH

84

2583

Value, in percent, that the active temperature control loop

 

 

 

output must go above for the reversing valve to switch.

 

 

 

Actual switchover is subject to the status of HEAT.COOL,

 

 

 

RVAL SW TIME, and HTG LOOPOUT or CLG LOOPOUT.

 

 

 

 

SWITCH LIMIT

85

2583, 2584

Active temperature control loop output must be less than

 

 

 

this value to switch between cooling mode and heating

 

 

 

mode. Actual switchover depends on SWITCH DBAND

 

 

 

being exceeded and is subject to SWITCH TIME being

 

 

 

expired.

 

 

 

 

SWITCH TIME

86

2583, 2584

Time, in minutes, that must expire to switch between cooling

 

 

 

mode and heating mode. Actual switchover depends on the

 

 

 

active temperature control loop being below the value of

 

 

 

SWITCH LIMIT and exceeding the value of SWITCH

 

 

 

DBAND.

 

 

 

 

CMP1 MlN OFF

87

2583

Minimum time, in minutes, that compressor 1 will remain

 

 

 

OFF before turning ON.

HTG1 MlN OFF

87

2584

Minimum time, in minutes, that heating compressor 1 will

 

 

 

remain OFF before turning ON.

 

 

 

 

CMP1 MlN ON

88

2583

Minimum time, in minutes, that compressor 1 will remain ON

 

 

 

before turning OFF.

HTG1 MlN ON

88

2584

Minimum time, in minutes, that heating compressor 1 will

 

 

 

remain ON before turning OFF.

 

 

 

 

RVAL SW TIME

89

2583

Length of time the compressor must be OFF before the

 

 

 

reversing valve can switch modes.
