VERVIEW

A ComfortNet inverter heating and air conditioning system uses
an indoor unit, outdoor unit and thermostat which digitally com-
municate with one another via a two-way communications path.
The thermostat sends commands to the indoor and outdoor
units. The thermostat may request and receive information from
both the indoor and outdoor units. This information may be dis-
played on the CTK04 thermostat. The indoor and outdoor units
also interact with one another. The outdoor unit may send com-
mands to or request information from the indoor unit. This two-
way digital communications between the thermostat and sub-
systems (indoor/outdoor unit) and between subsystems is the
key to unlocking the benefits and features of the ComfortNet
system.

Two-way digital communications is accomplished using only two
wires. The thermostat needs 24 VAC for power. 4 wires between
the indoor unit and thermostat plus two wires between the in-
door unit and outdoor unit are all that are required to operate
the system.

IAGNOSTICS

The heat pump’s diagnostics menu provides access to the most
recent faults.  The six most recent faults are displayed on the first
screen.  Six additional faults are displayed under fault history.
Faults are stored in order from most recent to least recent.  Any
consecutively repeated fault is stored a maximum of three times.
Example: A leak in the system, low refrigerant charge or an incom-
pletely open stop valve can cause the unit to flash error code E15.
This error code suggests that the unit is experiencing operation at
low pressure. The control will only store this fault the first three

consecutive 

times the fault occurs.

NOTE: 

It is highly recommended that the fault list be cleared after

performing maintenance or servicing the system.
