Programming MCS6, MCS12, MCS16
The de-icing feature has two different, selectable behavior modes when it is
used in conjunction with the control panel's built-in room air temperature sen-
sor. It attempts to compensate for any temperature discrepancy that the face-
plate sensor may experience. Although this discrepancy is not typical,
installation variables such as where the control panel is placed inside the
room (e.g. near an open door or in direct sunlight) can affect how accurately
it can read the actual room temperature.
By default with P-8 set to "1" (ON), the algorithm is applied assuming the
faceplate sensor may be reading the room temperature as much as 5 °F
(2.8 °C) greater than the actual evaporator temperature.
With programmable parameter P-8 set to "2", the temperature differential that
is applied to the faceplate sensor reading is increased to 7 °F (3.9 °C) for
even more extreme installations. Setting P-8 to "2" should only be used if a
setting of "1" does not prevent evaporator ice from forming.
Alternately, the installation of an optional alternate air temperature sensor
(located in the return air path) will greatly increase the effectiveness of the
de-icing feature, and this option should be considered whenever the face-
plate sensor cannot read the room temperature accurately.
P-9: High Water Temperature Limit
Use this feature to shut down the unit if the water in condenser coil rises to a
dangerously high level.
By default it is off, but it can be set between 100 and 150 °F.
The fault code is "PLF".
P-10: Display Brightness Control
The display brightness can be adjusted from 4 (dimmest) to 13 (brightest).
P-11: Fahrenheit or Celsius Selection
The default setting is "°F". Select "°C" for Celsius. Celsius readings are dis-
played in tenths, e.g. 22.2°.
P-12: Cycle Pump With Compressor
The pump can also be programmed to operate continuously or cycle on de-
mand.
➤ To program continuous operation select "On".
