Symptom
Humidistat Reading incorrectly
71 | Troubleshooting
Cause
1 "P" Trap too close to SAM-e
2 Condensate line not sloped
sufficiently
3 Steam line not insulated
1 Distributor tubes not seated
properly
2 Grommet Damaged
Cause
1 No power to blower pack
2 On/Off Thermostat not closing
Cause
1 Sensor out of calibration
2 Improper sensor location
3 Exposed to draft or heat source
4 No vapour barrier
Corrective Action(s)
1 "P" trap must be at least 12 in (30
cm) below header. Relocate if
required.
2 Ensure line is sloped sufficiently to
carry condensate produced.
3 If steam line is long condensate build
up could overload the SAM-e
condensate port. Insulate the steam
line to improve efficiency and install
condensate traps as required.
1 Push distributor tubes down until
support washer is resting on rubber
grommet.
2 Replace any damaged grommets
Corrective Action(s)
1a Check power connection.
1b Check blower pack fuses
2 Check wiring to thermostat replace if
it does not close when it is exposed to
steam.
Corrective Action(s)
1 Check reading against known reliable
instrument. If out of calibration it can
be field calibrated ±10%. Press
buttons together until calH
appears on the display. Press to
display the current calibration trim.
Adjust using  buttons. Press 
button when done.
2 Check that the humidistat is
positioned in a location
representative of room humidity.
3 Check that heat/cold fluctuations,
drafts, sunlight, doors, or vents are
affecting the reading.
4 Insure drafts cannot affect reading by
ensuing vapour barrier is in place and
working.
