Test Button
IMPORTANT: Press the Test Button for approximately ONE SECOND
to enter Test Mode. Pressing the Test button for a longer period can
possibly clear all fault code history

A test button on the DSB may be used to verify proper dissipation
system operation under each test condition listed below
pressing the test button, system will enter dissipation mode for 60
seconds to verify correct operation.

Required Minimum Dissipation Airflow
The Required Minimum Dissipation Airflow is listed in
on refrigerant charge, and must be met or exceeded in Continuous Fan
Mode. Refer to
Table 11
for available blower speeds and the associated
CFM performance.
!
PERSONAL INJURY AND PROPERTY DAMAGE
HAZARD
Required Minimum Dissipation Airflow must be met or exceeded with
the continuous fan speed selected.
Minimum Conditioned Space Area
The Minimum Conditioned Space Area
area allowed to be served by this unit for proper dissipation and is based
on the factory charge amount. The Minimum Conditioned Space Area
must not be used in unit sizing, as the small area, will likely result in
excessive short-cycling of the unit.
Example
A 36060 size unit will be installed in a residential home with a
conditioned space of 1800 sq. ft. (Conditioned space to be served
entirely by the unit). The low (blue) speed has been selected for
continuous fan and runs at .6 in. W.C. external static pressure.
From
Table
1, the minimum conditioned space area for the 36060 size is
106 sq. ft. Since 1800 sq. ft. is greater then 106 sq. ft., the conditioned
space is sufficient.
Also from
Table
1, the required minimum dissipation airflow for the
36060 size unit is 186 CFM. From
with continuous fan set to the low (blue) speed with an external static
pressure of .6 in. W.C. is 837 CFM. Since 837 CFM is greater than 186
CFM, the low speed is sufficient to deliver the required minimum
dissipation airflow.
Heat Anticipator Setting (Electro-Mechanical
Thermostats only)
The room thermostat heat anticipator must be properly adjusted to
ensure proper heating performance. Set the heat anticipator, using an
ammeter between the W and R terminals to determine the exact required
setting.
NOTE:
For thermostat selection purposes, use 0.18 amp for the
approximate required setting. Failure to make a proper heat anticipator
adjustment will result in improper operation, discomfort to the occupants
of the conditioned space, and inefficient energy utilization; however, the
required setting may be changed slightly to provide a greater degree of
comfort for a particular installation.
Transformer Protection
The transformer is of the energy-limiting type, however a direct short
will likely blow a secondary fuse. If an overload or short is present,
correct overload condition and check for blown fuse on Indoor Fan
