The SPA heater SPAWER driver system consists of a power relay (230V50Hz / 20A) which
plugs into the heater phase wire (between the SPA heater controller output and the heater
itself).
This relay is controlled by the heat pump control box either automatically or manually (boost).
As such, for the system to work properly, it is imperative to set the desired temperature of the SPA
water to the maximum on the SPA control screen (Ex: 38°), so the actual temperature setting will
now be done on the heat pump or via the smartphone application.
- In automatic spa heater mode: When weather conditions become difficult for the heat pump
(C26 setting: outside temperature below 15°C by default; adjustable from 0 to 20°C) and the de-
sired bathing temperature is 5°C higher than the measured water temperature (C27 setting), the
heater control relay is triggered. Thus the heating uses the electric heater of the SPA in addition to
the heat pump in order to reach the desired temperature.
- In manual spa heater mode: Regardless of the weather conditions, as soon as the temperature
difference between the set point and the measurement is greater than 2°C (C28 setting), the relay
is triggered. Thus the heating uses the electric heater of the SPA in addition to the heat pump in
order to reach the desired temperature.
For information, in automatic or cooling mode, the heater control option is inactive, it only operates
in heating mode.
To use this relay:
Setting the C32 setting = 1 to start the control (see advanced settings).
When the heat pump is on heating mode (automatic mode with heatin on): press the
for 3 seconds to switch the heater from one mode to another (automatic or manual).
In automatic mode, the (RECH) indicator is fixed. In manual mode, the (RECH) indicator flashes.
