SYNERGY3D INSTALLATION MANUAL
Startup
Before powering unit, check the
following:
Fuses, breakers and wire size are correct and match the •
name plate.
Low voltage wiring is complete.
•
Piping has been completed and the water system is •
cleaned and flushed.
Air is purged from the closed loop system.
•
Air is purged from buffer tank, hydronic system isolation •
valves are open, and water control valves or loop pumps
are wired.
Condensate line is open and correctly pitched.
•
Black/white and gray/white wires in unit control box have •
been removed if auxiliary heat has been installed.
DIP switches are set correctly.
•
Blower rotates freely and foam shipping support has •
been removed.
Blower speed is correct (DIP switch setting).
•
Air filter is clean and in position. •
Service/access panels are in place. •
Return air temperature is between 60-80°F in heating •
and 70-95°F in cooling.
Air coil is clean.
Hydronic Startup Instructions
Initiate a control signal to place the unit in the hydronic 1.
heating mode. Heating setpoint must be above the
water temperature of the buffer tank and/or load side
water loop.
Be sure that the water control valve or loop pumps are
2.
activated.
The compressor and load side circulating pump will
3.
energize after a time delay.
Using a digital thermometer measure the load side water
4.
entering the Synergy3D unit.
NOTe: Ensure that the sensing probe is in contact with
copper piping and that it is well insulated to prevent
measurement errors due to ambient room temperature.
Allow 2-3 minutes before measurement for best results.
Using a digital thermometer, measure the load-side 5.
water temperature leaving the Synergy3D unit. Refer
to Operating Parameters table and compare measured
temperature rise with data.
Adjust the heating setpoint below the water temperature
6.
of the buffer tank and/or load side water. Verify that
the compressor, load side circulating pump and water
control valve or loop pumps deactivate.
During test, check for excessive vibration, noise or water
7.
leaks. Correct or repair as required.
Set system to desired normal operating temperature to
8.
maintain desired comfort level.
Instruct the owner/operator in the proper operation 9.
of the hydronic temperature control and system
maintenance.
Forced Air Startup Instructions
NOTe:
On initial power-up a four-minute time delay will
occur.
Initiate a control signal to energize the blower motor. 1.
Check blower operation.
Initiate a control signal to place the unit in the cooling
2.
mode. Cooling setpoint must be set below room
temperature.
First stage cooling will energize after a time delay.
3.
Be sure that the compressor and water control valve or 4.
loop pumps are activated.
Verify that the water flow rate is correct by measuring
5.
the pressure drop through the heat exchanger using the
P/T plugs
and comparing to water Pressure Drop table.
Check the temperature of both the supply and discharge
6.
water. Refer to Operating Parameters tables.
Check for an air temperature drop of 15° to 25° F across
7.
the air coil, depending on the blower speed and entering
water
temperature. Refer to Operating Parameters tables.
Adjust the cooling setpoint above the room temperature
8.
and verify that the compressor and water valve or loop
pumps deactivate.
Initiate a control signal to place the unit in the heating
9.
mode. Heating setpoint must be set above room
temperature.
First stage heating will energize after a time delay.
10.
Check for an air temperature rise of 20° to 35° F across 11.
the air coil, depending on the blower speed and entering
water temperature. Refer to Operating Parameters
tables.
If auxiliary electric heaters are installed, adjust the
12.
heating setpoint until the electric heat banks are
sequenced on. All stages of the auxiliary heater
should be sequenced on when the thermostat is in the
“Emergency Heat” mode. Check amperage of each
element.
Adjust the heating setpoint below room temperature
13.
and verify that the compressor and water valve or loop
pumps deactivate.
During all testing, check for excessive vibration, noise or
14.
water leaks. Correct or repair as required.
Set system to desired normal operating mode and set
15.
temperature to maintain desired comfort level.
Instruct the owner/operator in the proper operation of
16.
the thermostat and system maintenance.
