STEP THREE
—————
ROUGH-IN WIRING
All electrical wiring terminates in the control base wiring chamber. The base has standard 7/8” (22 mm) knockouts which accept
common wiring hardware and conduit fittings. Before removing the knockouts, check the wiring diagram and select those sections
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 in (9 mm) to ensure proper connection to the control.
• Install the Outdoor Sensor 070, Boiler Sensor 071 and Mixing Sensor 071 according to the installation instructions in the
Data Brochure D 070 and run the wiring back to the control.
• If a DHW Sensor 071 is used, install the sensor according to the installation instructions in the Data Brochure D 070
and run the wiring back to the control.
• If a Mixing Return Sensor 071 is used, install the sensor according to the installation instructions in the Data Brochure
D 070 and run the wiring back to the control.
• If a tekmar Slab Sensor is used, install the slab sensor according to the installation instructions in the Data Brochure D
070 and run the wiring back to the control.
• If a Remote Display Module (RDM) 040 is used, install the RDM according to the installation instructions in the Data
Brochure D 040 and run the wiring back to the control.
• If a Remote Start / Stop Module 039 is used, install the module according to the installation instructions in the Data
Brochure D 039 and run the wiring back to the control.
• If a tekmar Zone Control is used, run the wires from the Zone Control to the 364. Refer to instructions supplied with
Zone Control.
• Run wire from other system components (pumps, boiler, actuating motors, etc.) to the control.
• Run wires from the 120 V (ac) power to the control. Use a clean power source to ensure proper operation. Multi-strand
16 AWG wire is recommended for all 120 V (ac) wiring due to its superior flexibility and ease of installation into the
terminals.

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
120 V (ac) Power
Connect the 120 V (ac) power supply to the Power L and Power
N terminals (7 and 6). This connection provides power to the
microprocessor and display of the control. As well, this con-
nection provides power to the Prim P1 terminal (8) from the
Power L terminal (7).
Mixing Demand
To generate a mixing demand, a voltage between 24 V (ac) and
240 V (ac) must be applied across the Mix Demand terminals
(1 and 2).
Boiler Demand
To generate a boiler demand, a voltage between 24 V (ac) and
240 V (ac) must be applied across the Boil Dem and Com Dem
terminals (3 and 4).
