Output Connections
System Pump Contact (Sys Pmp)
The Sys Pmp output terminal (5) on the 360 is a powered output.
When the relay in the 360 closes, 120 V (ac) is provided to the Sys
Pmp terminal (5) from the Power L terminal (3). To operate the
system pump, connect one side of the system pump circuit to ter-
minal (5), and the second side of the pump circuit to the neutral (N)
terminal 6.
Mixing Valve Actuator
Terminals 9, 10, and 11 are powered with 24 V (ac) from the con-
trol. There is no need to provide a separate 24 V (ac) power source
for the mixing valve actuator. R Opn (9) is connected to the open
terminal of the actuating motor and R Cls (10) is connected to the
close terminal of the actuating motor. C (11) is then connected to the
common terminal of the actuating motor.
Boiler Contact
The Boiler terminals (7 and 8) are an isolated output in the 360.
There is no power available on these terminals from the control.
These terminals are to be used as a switch to either make or break
the boiler circuit. When the 360 requires the boiler to fire, it closes
the contact between terminals 7 and 8.
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 (16 and 17). The outdoor sensor is used by the 360 to
measure the outdoor air temperature
Boiler Sensor
Connect the two wires from the Boiler Sensor 082 to the Com and
Boil terminals (13 and 14). The boiler sensor is used by the 360 to
measure boiler temperature.
Mixing Sensor
Connect the two wires from the Mixing Sensor 082 to the Com and
Mix terminals (13 and 15). The mixing sensor is used by the 360 to
measure the supply water temperature after the mixing valve. Nor-
mally the sensor is attached to the pipe downstream of the system
pump.
