Patterson-Kelley TBIG-03 ユーザーズマニュアル

all steps and safety checks are repeated.  The mo-
torized gas valves cannot reopen in the absence of 
ignition.  

11.  When the desired water temperature is reached, 

the operating control switch opens and the pro-
grammer is de-energized at Terminal 6 and the in-
dicator for "Heat" is turned off.  This action also 
de-energizes Terminal 9, thus closing both main 
gas valves and turning off the indicator for "Main 
Gas." 

12.  When the water temperature is reduced by the 

load on the system, the operating control switch 
will close again.  The operating sequence will re-
cycle to step 5, provided that the limits on water 
flow, gas pressure, and high temperature are all 
met.
