INSTALLATION INSTRUCTIONS THERMOSTAT
1 Enclosure installation ETS-05 line-sensing thermostat
Alternative mounting arrangements are shown above (4 mounting holes,
M6 clearance at 106 x 82 mm). For optimized temperature control install
the unit remote from sensor bulb. Locate enclosure at appropriate place
to avoid exposure to mechanical and thermal damage (do not mount on
pipe for high temperatures).
WARNING: When working in damp or wet conditions protect the
thermostat contents from water ingress, by closing lid when not working
on the assembly.
2 Enclosure installation ETS-05-A2-E (ambient sensing thermostat)
For optimized temperature control locate the thermostat:
• As indicated in the system design documentation
• So that the sensor is exposed to the coldest conditions
• So that the sensor is not exposed to direct sunlight where possible
• So that the sensor is exposed to the strongest wind
• To ensure that no snow can build up around the sensor
• To avoid exposure to mechanical and thermal damage
The ambient sensor is delivered as a loose item and needs to be installed
on site:
1. Screw sensor into M16 hole and tighten via locknut
2. Connect the sensor wires to the temperature sensor terminals:
• Terminal 1: red wire
• Terminal 2: red wire
• Terminal 3: white wire
For further details see section Termostat terminals and Wiring Sensor/
Failure mode select terminals.
