MAX COOL DEMAND — This variable displays the maxi-

mum cooling demand of all occupied linked zones, taking into

consideration the size of each zone as configured in the

Terminal Service Configuration Table. This is so that the size

of the zone will be considered when comparing its demand to

other zones.

Max Cool

Demand: Display Range delta 0.00 to 99.9 F

Network Access Read Only

MAX COOL DEMAND ZONE — This variable displays

the number of the zone that has the weighted maximum

cooling demand of all occupied linked zones. If all zones are

unoccupied then all zones will be included in the calculation.

Max Cool

Demand Zone: Display Range 0 to 31

Network Access Read Only

COOLING TIME GUARD — This variable displays the re-

maining time that the cooling mode must be active before a

mode change can take effect. The cooling time guard

timer becomes active whenever the COOL mode goes into

effect. This timer value is configured in the Master Service

Configuration Table.

Cooling

Time Guard: Display Range 0 to 255 minutes

Network Access Read Only

TIME GUARD OVERRIDE — This variable displays whether

there is a time guard override in effect. The override acts as a

one time override of any time guard in effect, heating or

cooling.

NOTE: The time guard override applies to the mode sent to the

air source. This is independent of the mode reselect function.

Forcing this point to Yes will allow the user to initiate a Time

Guard Override.

Time Guard

Override: Display Range Yes/No

Network Access Read/Write

HEAT MODE LOCK OUT — This variable displays whether

the system has been locked out of heating mode. If this

decision is forced to Yes, the system may not go into heating

mode regardless of how many zones are calling for heating.

Heat Mode

Lock Out: Display Range Yes/No

Network Access Read/Write

AVERAGE HEAT DEMAND — This variable displays the

average heating demand of all occupied linked zones, taking

into consideration the size of each zone as configured in the

Terminal Service Configuration Table. This is so that the size

of a zone will be considered when comparing its demand to

other zones. If all zones are unoccupied then all zones will be

included in the calculation.

MAX HEAT DEMAND — This variable displays the maxi-

mum heating demand of all occupied linked zones, taking

into consideration the size of each zone as configured in the

Terminal Service Configuration Table. This is so that the size

of the zone will be considered when comparing its demand to

other zones.

MAX HEAT DEMAND ZONE — This variable displays the

number of the zone that has the weighted maximum heating

demand of all occupied linked zones. If all zones are unoccu-

pied then all zones will be included in the calculation.

Max Heat

Demand Zone: Display Range 0 to 31

Network Access Read Only

HEATING TIME GUARD — This variable displays the re-

maining time that the heating mode must be active before a

mode change can take effect. The heating time guard timer be-

comes active whenever the HEAT mode goes into effect. This

timer value is configured in the Master Service Configuration

Table.

Heating

Time Guard: Display Range 0 to 255 minutes

Network Access Read Only

MODE RESELECT TIME — This variable displays the re-

maining time that must elapse before the mode change can take

effect. The user can override the timer by forcing this

value. This timer value is configured in the Master Service

Configuration Table.

Time Schedule Maintenance Table — The Time

Schedule Maintenance Table (OCCDEFME) displays occu-

pancy set points, the occupied mode and whether and override

is in progress. See Table 18.

MODE — This variable displays the current occupied mode

for the zone controller. If the zone controller is following its

own local schedule, this is the result of the local schedule

status.

NOTE: This information only applies to the locally configured

occupancy schedule or if the zone controller is configured to

be the Global Schedule Master. The information does not

apply to a zone if it is following a global schedule.

Mode: Display Range 0 or 1 (1 = occupied)

Network Access None

CURRENT OCCUPIED PERIOD — If the zone controller

is configured to determine occupancy locally, this variable will

display the current period determining occupancy.

Current Occupied

Period: Display Range 1 to 8

Network Access None

OVERRIDE IN PROGRESS — If an occupancy override is

in progress, this variable will display a yes.

Override In

Progress: Display Range Yes/No

Network Access None

OVERRIDE DURATION — This variable displays the num-

ber of minutes remaining for an occupancy override which is in

effect. If the number of override hours was downloaded, the

value will be converted to minutes.

Duration: Display Units minutes

Display Range 0 to 240

Network Access None

OCCUPIED START TIME — This variable displays the

time that the current occupied mode began.
