Attaching The Thermostat - Smart temp SMT?770 Installer Manual

Attaching the thermostat
Check that the position of the 8 DIP switches matches the requirements of the
equipment being controlled and the specific requirements of the user. Detailed
information on the 8 DIP switches can be found on page 6 of this manual.
Check the wiring matches that of the equipment the SMT‐770 is to control and that all
wiring is tight and not likely to short between adjacent wires. Equipment wiring
information can be found on page 12 of this manual.
If using the ModBus communication capability of the SMT‐770,
ensure the "A", "B" & "T" data wires are in the correct position as
an error here may affect the communication of the entire
network. See page 38 for detailed wiring of the communications
port of the SMT‐770.
Using masking tape or similar, block the hole in the wall
where the wiring enters the back of the thermostat to
prevent drafts that may travel down the inside of the wall
cavity affecting the accuracy of the internally fitted temperature sensor.
