STEP THREE
All electrical wiring terminates in the control base wiring chamber. The base has standard 22 mm knockouts which accept
common wiring hardware and conduit fittings. Before removing the knockouts, check the wiring diagram and select those sec-
tions of the chamber with common voltages. Do not allow the wiring to cross between sections, as the wires will interfere with
safety dividers which should be installed at a later time.
Power must not be applied to any of the wires during the rough-in wiring stage.
• All wires are to be stripped to a length of 3/8" (9 mm) to ensure proper connection to the control.
• Install the Outdoor Sensor 070e according to the instructions in the Data Brochure D 070e, and run the wiring back to
the control.
• If an Indoor Sensor 076e is used, install the indoor sensor(s) according to the instructions in the Data Brochure D 070e,
and run the wiring back to the control.
• If a Room Temperature Unit (RTU) 062e or 063e is used, install the RTUs according to the instructions in Data Brochure
D 062e, and run the wiring back to the control.
• If a Remote Display Module (RDM) 040e is used, install the module according to the instructions in the Data Brochure
D 040e, and run the wiring back to the control.
• If multiple zone controls are used, run two wires from one zone control to the next to create a chain.
• Run wiring from the system pump to the control.
• Run wires from each zone valve / pump to the control.
• Run wires from the 230 V (ac) power to the control. Use a clean power source with a 15 A circuit to ensure proper opera-
tion. The circuit breaker should be located near the control.
• Multi-strand 16 AWG wire is recommended for all 230 V (ac) wiring due to its superior flexibility and ease of installation
into the terminals.
STEP FOUR
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
230 V (ac) Power
Connect the 230 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 369e closes a dry contact between these
terminals when cooling is required.
System Pump Contact (Sys Pmp)
The Sys Pmp output terminal (17) on the 369e is a powered output. When the
relay in the 369e closes, 230 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 230 V (ac) power supply.
Zone Pumps and Zone Valves
Note: The zoning outputs are isolated terminals in the 369e. 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 unless the devices use the same voltage.
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.
