Application Notes
1 When no pipe sensor is used the main output controls
cooling and the secondary output controls heating.
2 The pipe sensor should be mounted on the main coil
input for water system operation and in the main duct
system for forced air operation.
3 The set point and operating mode will be retained on a
loss of power.
4 When using either a remote probe or pipe sensor, run
wiring away from any electrical motors or power wiring.
Power-Up Operating Sequence
Upon application of power, an MTA158 will go directly to
normal operation.
