Avoiding Problems
1) The “power-in” wires (RED & BLUE) ARE PO-
LARIZED, even though it’s an AC circuit! The RED
lead
must connect to the equipment’s HOT wire
(usually red), and the BLUE lead must connect to
the equipment’s COMMON wire (usually brown or
blue). REVERSING THESE LEADS CAN CAUSE
THE
ZebraStat’s CIRCUIT BREAKER TO TRIP.
2) If you are getting a strange LED indication in
either the CONTINUITY or ANALYZE modes, it
could be caused by having one of the ZebraStat’s
component switches ON. Leave all six switches
OFF for testing in either of these two modes.
3) In the CONTINUITY or ACTIVATE modes, all
thermostat switches should be OFF, and it must
not be calling for any heating or cooling. Strange
LED indications may appear on the Zebr aStat if
all thermostat functions aren’t completely ‘OFF’.
4) Some thermostats internally connect their ‘G’
and ‘Y’ terminals when in ‘Auto Fan’. (This will be
noticed in the CONTINUITY or ANALYZE modes.)
5) Some thermostats may activate the reversing
valve as soon as they are switched into ‘Heat’ or
‘Cool’. (CONTINUITY or ANALYZE modes.)
