Technical Settings - KwiKool KPHP Series Operation Manual

The heat function on KPHP Systems will require a
time delay for compressor operation; therefore,
there is a 2.5-minute delay in starting in Heat mode
and the Supply Air fan may cycle On to Off.
OPERATING MODE, AUTO COOL/ HEAT (optional)
1. Set the mode to HEAT/COOL. Both icons are displayed in this mode.
2. Enter the set point using the UP or Down arrows.
3. The system will automatically shift between cool or heat, based on demand within a 4-
degree temperature difference when turned ON. See the example below for more infor-
mation.
EXAMPLE
The set point is 72 F. The system is set in the HEAT/COOL Mode. The room reaches the set
point in COOL mode and the compressor cycles off. If the temperature in the room continues
to drop and gets down to 70 F, then the heat will come on until the set point of 72 is reached.
The heat then cycles off. If the temperature continues to rise and gets to 74 F, the system
switches to COOL mode and cools the space to the set point and then cycles off. The cooling
or heating icon flashes on and off to signify which operation is currently on and the system
operates the selected Fan feature for each function.
CYCLING OF POWER ON/OFF BUTTON
1. After the system has reached its set point in COOL or HEAT mode, it will automati-
cally cycle off, or the user may choose to turn the system off by selecting OFF.
2. If the unit cycles off or is turned off, the time delay will always activate when the sys-
tem again calls for cooling.
3. When cycling off by making the set point, the evaporator fan cycles off in Heating. In
Cooling, the fan stays on only if FAN is selected.
4. Heating or cooling will begin automatically when the temperature rises above or be-
low the set point, depending on the chosen mode.
5. Turning the system off manually will turn the evaporator fan off and not allow the sys-
tem to restart until the control is set to ON and the Return Air temperature is above
or below the set point.
6. In FAN mode the Supply Air fan only shuts down when OFF is selected.

TECHNICAL SETTINGS

Access into these operations is described later in this manual. Users and technical staff men-
us all have different features that allow access into settings and certain functions of the con-
trol based on information supplied by the engineers.
