TROUBLE SHOOTING
When 120VAC is supplied to i-Link controllers, the green
indicator light should be on. When the thermostat calls for heat,
both the red indicator light and the circulator should be on.
! If the green light is on and the circulator cannot be turned
on by the thermostat(red light is off), remove the thermostat
and put a piece of wire across the thermostat terminals (R/T
and W/T) to simulate thermostat calling for heat. If the
circulator can be turned on along with the red light, then check
the thermostat for functionality.
! If both green light and red light are on and the circulator
cannot be turned on, re-tighten the screws for the jumper on
terminal ZC and ZR in case of Cold Start Boiler Application and
try again.
! If red light is on all the time, check the thermostat for
functionality. Remove the thermostat from the i-Link controller
and put a piece of wire across R/T and W/T terminal to simulate
the thermostat calling for heat. If everything works properly,
then the thermostat is faulty.
If the green light is off, check the fuse and the presence of
120VAC power supply. If the fuse is fine and there is no power
output on 24VAC and COM terminals, the transformer needs
to be replaced.
