DIAGNOSTIC DISPLAY
Note: Because the pressure switches are monitored only when "Y1" (Input) is active, the code for
pressure switch open will not be seen when "Y1" is off. Instead, the “Normal Operation" or
“Anti-Short Cycle Lockout” code will be seen.
When a pressure switch opens and causes a short cycle lockout, the pressure
switch-open code will be seen until it closes, then the short cycle lockout code
will flash unless it has already expired.
W1 & W2 CAN BE USEDTO STAGE ELECTRIC HEAT
ACCESSORY ON 15 & 20KW MODELS.
5, 7.5, & 10KW HEATER ACCESSORIES FUNCTION
OFF W1 ONLY.
