SECTION 5 – SEQUENCE OF OPERATION
The following criteria must be met for Morning Warm
up operation:
• Morning Warm up will only work on a VAV sys-
tem.
• Morning Warm up will only work when the in-
ternal scheduling feature is used. It will not work
using a hard wired or communicated Occupied
command.
• Morning Warm up will only function during the
first occupied period of each day .
Sequence of Operation
On Morning Warm up the following applies:
• One hour before the beginning of the occupied pe-
riod the Simplicity Elite control will energize the
supply fan circuit.
• The Simplicity Elite control will keep the econo-
mizer damper closed.
• After 5 minutes of supply fan operation the Sim-
plicity Elite control will compare the return air
temperature to the “MORNING WARM UP/VAV
RETURN AIR TEMP SETPOINT”
.
• If the return air temperature is 2.0° F or more be-
low the “ MORNING WARM UP/VAV RETURN
AIR TEMP SETPOINT” the Simplicity Elite con-
trol will energize all the available heat.
• If the return air temperature is not 2.0° F or more
below the “MORNING WARM UP/VAV RETURN
AIR TEMP SETPOINT”
the Simplicity Elite con-
trol will continue supply fan operation while con-
tinuing to monitor the return air temperature.
• When the return air temperature is equal to or
above the “MORNING WARM UP/VAV RETURN
AIR TEMP SETPOINT” heating operation will be
de-energized.
• During this time the heat will cycle ON and off
based on the comparison of the return air tempera-
ture to the “MORNING WARM UP/VAV RETURN
AIR TEMP SETPOINT”.
•
A
fter one hour of operation the Simplicity Elite
control will go into the Occupied mode and open
the economize to the minimum position.
• Heating operation will continue until the return
air temperature is equal to or above the
“MORN-
ING WARM UP/VAV RETURN AIR TEMP
SETPOINT”.
HYDRONIC HEAT
The following parameters must be programmed to use
Hydronic Heat:
• “HEATING MODE ENABLED FOR OPERA-
TION” must be enabled using Parameter 54 under
the PROGRAM key of the Simplicity Elite con-
trol board or under the HEATING SETUP tab in
the Simplicity PC software package.
• “HYDRONIC HEATING ENABLED” must be en-
abled using Parameter 18 under the PROGRAM
key of the Simplicity Elite control board or under
the HEATING SETUP tab in the Simplicity PC
software package.
•
“HYDRONIC HEATING STAGE #1 SUPPLY AIR
SETPOINT” must be programmed using Parame-
ter 19 under the PROGRAM key of the Simplicity
Elite control board or under the HEATING SET-
UP tab in the Simplicity PC software package.
• “HYDRONIC HEATING STAGE #2 SUPPLY AIR
SETPOINT”
must be programmed using Parame-
ter 20 under the PROGRAM key of the Simplicity
Elite control board or under the HEATING SET-
UP tab in the Simplicity PC software package.
Sequence of Operation
On Constant Volume units whenever there is a call for
the 1st stage of heating operation the Simplicity Elite
control will vary a 2 to 10VDC output to the hydronic
valve to try and maintain the supply air temperature
to within plus or minus 1.0° F of the “HYDRONIC
HEATING STAGE #1 SUPPLY AIR SETPOINT” . The
output to the valve can be found at terminal “HWV+”
and “HWV-“ at connector P14 on the Simplicity Elite
control board.
On Constant Volume units whenever there is a call for
the 2nd stage of heating operation the Simplicity Elite
control will vary a 2 to 10VDC output to the hydronic
valve to try and maintain the supply air temperature
to within plus or minus 1.0° F of the “HYDRONIC
HEATING STAGE #2 SUPPLY AIR SETPOINT” .
On a VAV unit whenever there is a call for heat the
Simplicity Elite control will vary the 2 to 10VDC
output to the hydronic valve to try and maintain the
supply air temperature to within plus or minus1° F of
the
“HYDRONIC HEATING STAGE #2 SUPPLYAIR
SETPOINT”.
