Located under the electrical control box cover.
Ambient Temperature Sensor
The Ambient Temperature Sensor senses room temperature. This sensor provides room temperature information to the
ECU for calculation of inverter capacity and temperature control.
Piping Temperature Sensor
The Piping Temperature Sensor senses indoor coil temperature in the cooling mode and in the heating mode. This sensor is
used for Anti Freezing and Anti Cold Blow cycles. The sensor also provides critical temperature information to the ECU that
may be used in frequency adjustments.
The Mid-Static Ducted unit has a built in condensate pump. The pump is connected to the circuit board. The pump is
energized whenever the Float Switch indicates that water needs to be pumped from the cassette. The float switch
connects onto the circuit board.
The float switch and pump are located behind the removable insulated cover next to the electrical control box. The pump
is hermetically sealed and requires no maintenance. The float switch is a normally closed switch, that opens as water rises.
The float switch requires no maintenance.
Gravity Drain Ports
The indoor unit has the option for either gravity drain systems or the use of an internal condensate pump with float switch.
The pump is capable of minimal lift. If high lift is required, the water from the Mid-Static Ducted unit should be pumped to a
field supplied condensate pump that is capable of high lift.
The unit comes shipped with a WiFi module that provides control via a smartphone app.
