the UP and DOWN buttons for 3 seconds to exit REMOTE
Mode.
On HEAT/COOL models, the control displays “Remote
Pool” on the first line of the display while the 2nd line
displays “Cool”, “Heat” or “Auto”. Factory default is “Cool”.
The control uses the value selected when the MENU button
is pressed to advance to the next item. This programming
is done from the Installer/Service menus.
Pool Heat Mode
The control is equipped with a mode which will automatically
heat the pool to the heating setpoint established in the
User’s menu.
Pool Cool Mode (HEAT/COOL
models ONLY)
The control is equipped with a mode which will automatically
cool the pool to the cooling setpoint established in the
User’s menu.
Pool Auto Mode (HEAT/COOL
models ONLY)
The control is equipped with a mode which will
automatically heat and cool the pool within the range of
the heating setpoint plus the Cooling Deadband (2-10°F
(1.1-5.5°C) adjustable – default 6°F (3.3°C)) established
in the Installer/Service Sub-menu. Example – pool heating
setpoint set at 80°F (27°C) and Cooling Deadband set at
6°F – unit will automatically heat the pool if the temperature
drops below 80F (27°C) and will automatically cool the
pool if the temperature is above 86°F (30°C).
TIMED SPA Mode
The control is equipped with a mode which will heat the
spa to the Spa Setpoint temperature for a specified period
of time selected in the TIMED SPA mode setup. NOTE:
The Spa setpoint temperature CANNOT be changed when
operating in this mode. This functionality will override all
other program settings for the period of time selected by
the user during the TIMED SPA initiation.
A
WARNING:
If the Spa heating (in a pool/spa
system) is controlled by an external controller, 3-way
valves MAY need to be manually adjusted in order to
use the TIMED SPA feature of this heat pump. Failure
to properly adjust the 3-way valves may result in
overheating of the pool water or other undesirable
results.
1. To activate the TIMED SPA feature, press the MENU
button until “TIMED SPA” is displayed on the top line
of the display.
2. Press the UP or DOWN buttons to select the desired
duration of spa heating (up to a maximum duration of
6 hours in 15-minute increments).
3. The timer will start to count down from the selected
period of time and the unit will operate to heat the
spa water based on the previously selected spa
setpoint temperature setting.
When the TIMED SPA timer has expired, the control will
return to the previous mode that it was in when TIMED
SPA was selected.
Fault History
The control is equipped to maintain fault history in the
Installer/Service menu. It will retain the last 10 faults
(starting with the most recent). If the fault history exceeds
10 events, the earliest fault drops off when a new fault
occurs. NOTE: There is no time/date stamp associated
with each fault. This history is intended to simply show
what faults the unit has experienced.
When the “Faults Last” shows on the display, pressing the
UP button toggles to the most previous fault. Pressing the
UP button toggles through the recorded faults. The faults
are labeled on the first line of the display as Faults Last,
Faults 2, Faults 3, etc.
Consecutive identical faults are only stored once.
Run Hours/Cycles
The control is equipped to monitor the number of run hours
of the unit and the cycles of operation. This is accessible
through the Installer/Service menu. These values are not
resettable. The “Run Hours” tracks the number of hours
that the compressor has been energized. This data is
stored in non-volatile memory each time the demand for
heat is satisfied. Hours and minutes are stored, although
only hours are displayed. The “Cycles” tracks the number
of times that the compressor has been energized.
Compressor Start Delay
The control is equipped with a compressor start delay to
prevent short-cycling of the compressor. The control will
not energize a compressor unless the compressor has
been off for at least 3-minutes. When this situation arises,
the display shall read “Comp Start Delay” until the timer
clears and the compressor starts.
Minimum Run Time
To ensure proper operation of the compressor and longest
life, the control has a minimum run time for the compressor
of 3-minutes. If the setpoint is reached within 3-minutes,
the compressor will continue to run for 3-minutes unless
(1) the high pressure switch trips, (2) the water pressure
switch trips, (3) the high temperature limit is reached, or
(4) the user selects “OFF” mode.
