Using recorded Low Heat (LH)
and High Heat (HH) v
alues,
calculate the Heat Load (HL)
using:
HL=(228 X LH) + (350 X HH)
Is HL < 3648?
Is HL > 5600?
Calculated Low Heat (LH) on
time will be 16 minutes
Calculated Low Heat (LH) on
time will be 0 minutes
Unit will initiate the ne
xt cycle
in Low Heat to the nearest minute f
or a period of time as
calculated b
y the f
ollowing:
LH
run time
= (5600-HL)/122
Unit will initiate the ne
xt cycle in
Low Heat f
or a maximum of 16
minutes bef
ore initiating High Heat
if the call f
or heat still e
xists
Unit will initiate the ne
xt cycle in
High Heat until the
ther
mostat is satisfied.
The ne
xt cycle will be initiated
with the calculated Low Fire run time bef
ore initiating High Heat if
a call f
or heat is still present
The Low Heat and High Heat run times for this cycle will be
as calculated
Ther
mostat is satisfied.
