Test Procedure
Measure resistance of the
following terminal
① Terminal: 1 (COM) - 2
② Terminal: 1 (COM) - 3
③ Terminal: 2 - 3
Measure resistance of terminal
to terminal
Temperature condition:
58°F ~ (10~40°C)
58°F ~ 104F (10~40°C)
Measure resistance of the
following terminal
① Valve 1 terminal
② Valve 2 terminal
Measure resistance of terminal
to terminal
Measure resistance of terminal
to terminal
① Open at 370°F ((Maximum)
② Close at 320°F
Check result
① Resistance value 10Ω
② Resistance value 10Ω
③ Resistance value 20Ω
Resistance value 10Ω
① Resistance value > 1.5 kΩ
