be installed at a later time.
Power must not be applied to any of the wires during the rough-in wiring stage.
•
Optional If an Outdoor Sensor 070 is used, install it according to the instructions in the Data Brochure D 070 and run two wires back
to the control.
• If an Indoor Sensor 076 is used for any zone, install the Indoor Sensor(s) according to the instructions in the Data Brochure 070
and run the wiring back to the control.
• If an RTU 054 is used, install the RTU(s) according to the installation instructions provided in the Data Brochure D 054 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 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.
• Run wiring from the system pump to the control.
• Run wires from each zone valve / pump to the control.
STEP FOUR
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 in firmly.
Powered Input Connections
120 V (ac) Power
Connect the 120 V (ac) power supply to terminals
Power N — L (3 and 4).
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 terminals
Com Sen — Out
Sen (16 and 18). The Outdoor Sensor measures the outdoor air temperature.
Zone Control Input and Output
Connect a wire between the
Com Sen (16) terminals on each 367. Connect the Zo Out
terminal on the first 367 to the
Zo In terminal on the second 367. With several Zone
Controls, connect the
Zo Out terminal on the second 367 to the Zo In terminal on the
third 367 and continue this process for each additional 367. The
Zo Out terminal on the
last 367 in the chain can be connected to the
Zo In terminal on a tekmar reset control.
Note The wires from the Zone Control are polarity sensitive. The system will not
operate if the wires are reversed.
UnOccupied Switch
If an external timer or switch is used, connect the two wires from the external dry contact
switch to the
UnO Sw — Com Sen(14 and 16) terminals. When these terminals short
together, the control registers an UnOccupied signal.
Note If an external switch is closed between the terminals
UnO Sw — Com Sen
(14 and 16), the 24 hr. Timer is disabled and the Optimum Start / Stop
information is lost. It is recommended that either the 24 hr. Timer or an external
timer / switch is used, not both at the same time.
One Stage RTU and Indoor Sensor Connections
RTUs and Indoor Sensors provide indoor temperature feedback to the control. It is best
to start the One Stage zones at output relay
5 and work towards output relay 1.
Common block for
RTU 5 and RTU 6
• If the common block is used for a single One Stage heating zone, connect the RTU
or Indoor Sensor to terminals
Com Sen — RTU 5 (11 and 12).
• If the common block is used for 2 One Stage heating zones, connect one RTU or
Indoor Sensor to the
Com Sen — RTU 5 (11 and 12) terminals and connect the
other RTU or Indoor Sensor to the
Com Sen — RTU 6 (11 and 13) terminals.
Common block for
RTU 4 and RTU 3
• If the common block is used for a single One Stage heating zone, connect the RTU
or Indoor Sensor to terminals
Com Sen — RTU 3 (8 and 9).
• If the common block is used for 2 One Stage heating zones, connect one RTU to
the
Com Sen — RTU 3 (8 and 9) terminals and connect the other RTU to the Com
