Heat Mode 

 

When a  call  for  heat (“W”)  is received  from the  thermostat, if the  “Cool”  mode  is  not already 
active, the “T-T” terminal is energized and the blower on delay is started. The on-off pattern of 
DIP  switch  SW2  (positions  1  and  2)  select  one  of  four  blower  on  delay  values  (see  Table  7). 
When the delay time has elapsed, the “HEAT” blower speed is energized.  The control remains 
in steady heat mode until the thermostat is satisfied. When the call for heat signal is removed, the 
“T-T”  terminal  is  de-energized  and  the  blower  off  delay  is  started.  The  on-off  pattern  of  DIP 
switch SW2 (positions 3 and 4) select one of four blower off delay values (see Table 7). When 
the delay time has elapsed, the “HEAT” blower speed terminal is de-energized.

Motor Blower Speed   

 

  Three interconnected blower speed outputs are provided. A “G” call for fan will provide power 

to the LOW speed tap only. A  “W” heat call will provide power to the Heat speed tap only.  A 
“Y” cooling call will provide power to the Cool speed tap only. 

 

In  the  case  of  thermostat  calls  for  “Y”  and  “W”  together,  blower  speed  selection  will  be 
determined by the input that was first initiated. In the case where the control is in a cooling mode 
with both “Y” and “W” inputs energized and then the “Y” input is removed, the cooling blower 
off time will  be executed prior to the control switching  into a heating  mode. In the case where 
the control is in a heating mode with both “Y” and “W” inputs energized and then the “W” input 
is  removed,  the  heating  blower  off  time  will  be  executed  prior  to  the  control  switching  into  a 
cooling mode. In the case where a call for fan “G” already exists and either a “W” or a “Y” call 
is  initiated,  the  blower  speed  will  switch  to  the  respective  “W”  or  a  “Y”  speed  following  the 
blower on delay for that call.
