CONTROL ADJUSTMENTS 

 

The  leaving  chilled  water  temperature  is 

controlled  to  a  standard  rating  point  of 
44.6°F 

(7°C)

.    The  operating  dead  band  of 

Low  Fire  is  3.6°F 

(2°C)

.    The  Low  Fire  dead 

band  is  not  adjustable.   The  operating  dead 
band  of  High  fire  is  7.2°F 

(4°C)

.    The  High 

Fire dead band can be cut  in half by setting 
Dip  Switch  2  on  the  I/O  Board  to  ON.    The 
leaving  chilled  water  temperature  can  be 
adjusted  using  the  TC  potentiometer  on  the 
CPU  Board.    The  leaving  chilled  water  set 
point  can  be  set  in  a  range  of  40.1°F 

(4.5°C)

 

to 59.9°F 

(15.5°C)

Similarly,  the  leaving  hot  water  standard 

rating  point  is  131°F 

(55°C)

.    The  Low  Fire 

dead  band  and  High  Fire  dead  bands  are 
identical  to  Cool  mode,  but  the  High  Fire 
dead  band  can  be  cut  in  half  by  setting  Dip 
Switch  4  on  the  I/O  Board  to  ON.    The 
leaving  hot  water  temperature  can  be 
adjusted  using  the  TH  potentiometer  on  the 
CPU Board.  The leaving hot water set point 
can  be  set  in  a  range  of  122.9°F 

(50.5°C)

  to 

140.9°F 

(60.5°C)
