Expansion Relays
[Optional]
Steps of Reheat.: 2
If you require the VAV/Zone Controller to control reheat for the zone
it is installed in, you must include a relay expansion board and then
confi gure the number of heating stages (1, 2, or 3) that it will be control-
ling whenever there is a heating demand in the space. Enter
<0> if you
don’t require this option.
Confi guration Screen #6 - Proportional
Heating Signal
XX Box Cnfg IDXXXX
Proportional Heating
Signal..: 0 - 10 VDC
[0 = 0-10 1 = 2-10]
Select this option to change the range of the proportional heat output
from 0-10 VDC to 2-10 VDC.
Confi guration Screen #7 - Box Heat Allow
XX Box Cnfg IDXXXX
Allow Box Heat With
HVAC Heat....: NO
[0=NO 1=YES]
Set this option to 1 = YES to allow the Heating Relay’s Controlling Box
Heat to remain on even when the HVAC unit is in Supply Air Heating
Mode. This is used as a method to provide supplemental heat if for some
reason the HVAC heat cannot satisfy the heating demand.
Confi guration Screen #8 - Main Fan Status
XX Box Cnfg IDXXXX
This Unit Needs Main
Fan Status...: NO
[0=NO 1=YES]
This setting only applies to the unoccupied mode of operation. Select
1=YES to activate the heating stages only when the main fan is operating
on non-fan terminal units. For series fan terminal units, if this setting
is set to 1=YES, the series box fan will only run when the main HVAC
unit fan is running or when a space heating demand is made. For series
fan terminal units, if this setting is set to 0=NO, the series box fan will
only run when a space heating demand is made. This setting has no ef-
fect on the parallel fl ow fan terminal unit.
Confi guration Screen #9 - Push-Button
Override
XX Box Cnfg IDXXXX
Push-Button Override
Group ID #: 1
During Unoccupied Mode, all zones with a corresponding Group ID #
will resume Occupied operation whenever any of the zones in that group
has its push-button depressed to initiate an override condition. This al-
lows you to group zones in various areas of the building. For example,
individual tenants with several offi ces could restore occupied mode for
just their zones and not affect other zones in the building.
If you don’t want a specifi c zone to be a part of any group, enter <0>
for its Group ID #.
Confi guration Screen #10 - Dump Zone
XX Box Cnfg IDXXXX
Is This A Dump Zone
(No Actuator): NO
[0=NO 1=YES]
A “Dump Zone” is used when you want to control a duct heater or
baseboard heater independently. A VAV/Zone Controller board with a
relay expansion board is used for this purpose. No damper or actuator is
used. If you need to control an auxiliary heater, select 1=YES; otherwise,
be sure it is set to 0=NO.
Confi guration Screen #11 - HVAC Unit is on
Separate Loop
XX Box Cnfg IDXXXX
HVAC Unit is on
Separate Loop: NO
[0=NO 1=YES]
If this system has 1 HVAC unit controlling boxes on multiple loops
and the HVAC unit is on a different loop than this box, select 1=YES;
otherwise, be sure it is set to 0=NO.
