Outdoor Temperature Sensor Connections

Section 2.1

Control Installation

1. Install outdoor temperature sensor on outside

of structure.

2. Connect field supplied wiring to terminals

inside of sensor. Ensure wiring is run through

strain relief at bottom of sensor housing.

Reinstall sensor cover onto sensor backing.

3. Run field supplied wiring between sensor and

controller sub-base.

4. Locate wiring connections on sub-base of

Versatronik COMO OT Room Controller.

5. Wire to terminals 5 and 6 in sub-base of

Versatronik COMO OT.

Install Versatronik Como OT onto sub-base for

programming or adjustments.

WARNING

When extending wire there is the possibility of

exposure to electromagnetic interference. Avoid

running wires beside or near high voltage 120/240

VAC conductors. If proximity to high voltage

conductors cannot be avoided, use stranded, twisted

pair of shield design wire. Ensure that only one end of

the shielding is grounded.

Important

The outdoor temperature sensor should be

mounted 2 to 2.5 metres above ground level on

the north or north-west facing wall of the

building. In the case of multi-storey buildings, it

should be mounted in the upper half of the

second storey. Make sure that the sensor is not

located over windows, doors and air vents, nor

immediately beneath a balcony or guttering. Do

not paint over the outdoor temperature sensor

housing.
