(12) terminal on the last 368 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 (11 and 13) 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

(11 and 13), 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.

Common block for 

RTU 1 and RTU 2

• If the common block is used for a single One Stage heating zone, connect the RTU

or Indoor Sensor to terminals 

Com Sen — RTU 1 (5 and 6).

• If the common block is used for 2 One Stage heating zones, connect one RTU or

Indoor Sensor to the 

Com Sen — RTU 1 (5 and 6) terminals and connect the other

RTU or Indoor Sensor to the 

Com Sen — RTU 2 (5 and 7) terminals.

Common block for 

RTU 3 and RTU 4

• 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

Sen — RTU 4 (8 and 10) terminals.

Two Stage RTU and Indoor Sensor Connections

Common Block for 

RTU 1 and RTU 2

• If the common block is used for a Two Stage heating zone, connect the RTU or

Indoor Sensor to terminals 

Com Sen — RTU 2 (5 and 7).

Common Block for 

RTU 3 and RTU 4

• If the common block is used for a Two Stage heating zone, connect the RTU or

Indoor Sensor to terminals 

Com Sen — RTU 4 (8 and 10).

Output Connections

System Pump

Connect the live (L) side of the 120 V (ac) pump circuit through the 

System Pmp —

System Pmp (1 and 2) terminals. The control closes a dry relay contact between these
terminals when operation of the system pump is required.

Zone Pumps and Valves

Note

Do not connect a zone pump and zone valve circuit to the same 

Com terminal.

• If relay 

1 is used, connect the zone pump or zone valve circuit to the Com 1-2 — 1

(15 and 16) terminals on the control.

• If relay 

2 is used, connect the zone pump or zone valve circuit to the Com 1-2 — 2

(15 and 17) terminals on the control.

• If relay 

3 is used, connect the zone pump or zone valve circuit to the Com 3-4 — 3

(18 and 19) terminals on the control.

• If relay 

4 is used, connect the zone pump or zone valve circuit to the Com 3-4 — 4

(18 and 20) terminals on the control.

STEP FIVE 

 TESTING THE WIRING 

Each terminal block must be unplugged from its header on the control before power
is applied for testing. Pull straight down to unplug the terminal block.
