The SMT-131 is powered by 24VAC and requires the 24VAC
active and neutral to be connected to the “R” (active) and “C”
(Neutral) terminals for the SMT-131 to function. The 24VAC
applied to the SMT-131 “R” terminal is switch back through
the 2A relays to the equipment. Note the drawing provided here.
Caution - Although the SMT-131 is a robust device, wiring errors can potentially
damage the thermostat. Warranty does NOT cover this damage. Take care when
wiring 24V near sensor inputs or the Modbus communications terminals.
