H.PMP – Heat Pump Mode
This setting is only visible if a SV Series heat pump is connected and defines heat pump operating mode.
The available operating modes are as follows:
AUTO Heat pump will heat and cool
HEAT Heat pump will only heat (Default)
COOL Heat pump will only cool
OFF Heat pump disabled
H.ELE – Heat Pump + SV Element Boost
This setting is only visible if a SV Series heat pump is connected and defines how the SV Mini electric heating
element operates with a heat pump. By default, this setting is set to OFF which disables the electric heater
using only the heat pump for heating. Set to ON to allow the electric element to run in conjunction with the
heat pump to boost heating speed if the water temperature is 2 o C or more below set temperature point or
the heat pump has been operating for more than 1 hour and set point has not been achieved. The H.ELE setting
choices are:
OFF SV element disabled (heat pump only)
ON SV e Heat Pump for heating
HEATING CONTROL & PROTECTION
Fast Heat Cycle / Freeze and Overheat Protection Fast Heat Cycle
After initial mains power on the SV Mini will perform a fast heat up cycle that enables continuous demand
heating regardless of programmed/default sleep timer. Once the set temperature has been reached the fast
heat up cycle is cancelled and normal operation resumes and sleep timer is obeyed. The purpose of a fast heat
up cycle is to help the spa reach set temperature as soon as possible after it has been powered up. For new
spas or spas refilled with cold water it is desirable not to have sleep time delaying the time to takes for the
spa to reach set temperature point
.
NOTES:
1. A fast heat up cycle is cancelled by manually forcing the filtration pump to OFF via the keypad
2. For new spas or when a spa has just been refilled it is common for spa users to test the operation of each pump when
the power is first turned on. This process will cancel the fast heat up cycle. After completing testing of the spa functions
remember to reset mains power if you wish to reactivate fast heat up cycle.
Freeze Protection
Freeze protection will be activated whenever the water temperature drops below 4
o
C. It runs back to back 10
minute sanitise cycles and displays “WARM” on the LCD. It also runs each spa accessory (i.e. jet pumps and air
blower) in sequence to run water through the pipe work whilst running the filtration pump and heater. During
the “WARM” cycle the heater and heat pump (if fitted) will operate however heater load shedding may occur
when accessory pumps are running depending on control and load shed settings.
At the end of each 10 minute “WARM” cycle the water temperature is checked. If it is above 4 o C freeze
protection stops and the controller returns to its prior state. If the temperature is not above 4 o C another cycle
will run.
