Boiler
If a boiler is connected to the terminals Boiler — Boiler (18 and 19), make sure power to the boiler circuit is off and install a jumper
between the terminals. When the boiler circuit is powered up, the boiler should fire or if a Boiler Control is used, the Boiler Control
should register a Heat Demand. If the Boiler Control does not register a Heat Demand, check the wiring between the terminal block
and the Boiler Control. If the boiler does not turn on, refer to any installation or troubleshooting information supplied with the boiler
and/or Boiler Control. If the boiler operates properly, disconnect the power and remove the jumper.
DHW Pump or Valve
If a DHW pump or DHW valve is connected to the terminals DHW Pmp / Vlv — DHW Pmp / Vlv (20 and 21), make sure the power
to the pump or valve circuit is off and install a jumper between the terminals. When the DHW circuit is powered up, the DHW pump
should turn on or the DHW valve should open completely. If the DHW valve or pump does not operate, check the wiring between
the terminals and the pump or valve and refer to any installation or troubleshooting information supplied with these devices.
Zone Pump or Valve
• If a zone pump or zone valve is connected to the terminals Com 3-4 —4 (27 and 29), make sure power to the pump or valve circuit
is off and install a jumper between the terminals Com 3-4— 4 (27 and 29). When the zone circuit is powered up, the zone pump
should turn on or the zone valve should open completely. If no response occurs, check the wiring between the terminal and the
pump or valve and refer to any installation or troubleshooting information supplied with these devices.
• If a zone pump or valve is connected to the terminals Com 3-4 — 3 (27 and 28), follow a similar procedure as described above
for the zone 4 relay.
• If a zone pump or valve is connected to the terminals Com 1-2 — 2 (24 and 26), follow a similar procedure as described above
for the zone 4 relay.
• If a zone pump or valve is connected to the terminals Com 1-2— 1 (24 and 25), follow a similar procedure as described above
for the zone 4 relay.

• Make sure all power to the devices and terminal blocks is off and remove any remaining jumpers from the terminals.
• Reconnect the terminal blocks to the control by carefully aligning them with their respective headers on the control and then pushing
the terminal blocks into the headers. The terminal blocks should snap firmly into place.
• Install the supplied safety dividers between the unpowered sensor inputs and the powered 120 V (ac) or 24 V (ac) wiring chambers.
• Do not apply power to the control until the adjustment dials and DIP switches are properly set for your application. See the Settings
section of this brochure for details on how to set the dials and DIP switches.
• Once the settings are complete, apply power to the control. The operation of the control on power up is described in the Sequence
of Operation section of this brochure.
Settings
Before adjusting the dial settings, read through the sequence of operation section of this brochure to ensure that you understand how
the control operates.

First determine the length of time required for the UnOccupied period and turn the
UnOccupied Duration dial to the desired duration length. If the dial is set to 24 hours, the
370 remains in UnOccupied mode continuously. If the dial is set to 0 hours, the 370
remains in Occupied mode continuously.
Press the Start button at the desired starting time for the UnOccupied period. Once the
Start button is pressed, the 370 enters the UnOccupied period at the same starting time
each day.
Example: The user wants an UnOccupied period starting at 10 pm and ending at 6 am.
The Unoccupied Duration dial is set to 8 hours and the Start button is pressed
at 10 pm. Once the Start button is pressed, the control goes into UnOccupied
mode from 10 pm until 6 am the next morning. This cycle is repeated 7 days
a week.
