ELECTRICAL CONNECTIONS TO THE CONTROL

The installer should test to confirm that no voltage is present at any of the wires. Push the control into the base and slide it down until
it snaps firmly into place.

Powered Input Connections

115 V (ac) Power

Connect the 115 V (ac) power supply to the

Power L and Power N

terminals (18 and 19). This connection provides power to the
microprocessor and display of the control. As well, this connection
provides power to the

Sys Pmp terminal (17) from the Power L

terminal (18).

Output Connections

Cooling Contact

If a cooling system is used, connect the wires from the cooling unit
to the

Cooling terminals (15 and 16) on the control. The 369 closes

a dry contact between these terminals when cooling is required.

System Pump Contact (

Sys Pmp)

The

Sys Pmp output terminal (17) on the 369 is a powered output.

When the relay in the 369 closes, 115 V (ac) is provided to the

Sys

Pmp terminal (17) from the Power L terminal (18). To operate the
system pump, connect one side of the system pump circuit to the
Sys Pmp terminal (17), and the second side of the pump circuit to
the neutral (N) side of the 115 V (ac) power supply.

Zone Pumps and Zone Valves

Note: The zoning outputs are isolated terminals in the 369. There
is no power available on these terminals from the control. Do not
connect a zone pump and zone valve circuit to the same

Com

terminal.

If zone 1 is used, connect the zone pump or zone valve circuit to
the

Com 1-2 and Zn 1 (7 and 6) terminals on the control.

If zone 2 is used, connect the zone pump or zone valve circuit to
the

Com 1-2 and Zn 2 (7 and 8) terminals on the control.

If zone 3 is used, connect the zone pump or zone valve circuit to
the

Com 3-4 and Zn 3 (10 and 9) terminals on the control.

If zone 4 is used, connect the zone pump or zone valve circuit to the

Com 3-4 and Zn 4 (10 and 11) terminals on the control.

If zone 5 is used, connect the zone pump or zone valve circuit to the

Com 5-6 and Zn 5 (13 and 12) terminals on the control.

If zone 6 is used, connect the zone pump or zone valve circuit to the

Com 5-6 and Zn 6 (13 and 14) terminals on the control.

Sensor and Unpowered Input Connections

Do not apply power to these terminals as this will damage
the control.

Outdoor Sensor

Connect the two wires from the Outdoor Sensor 070 to the

Com

and

Out terminals (4 and 5). The outdoor sensor is used by the 369

to measure the outdoor air temperature.
