The last 20 error codes are stored, where 1 is the most recent.
Yes/No. Yes = Restores factory defaults and removes stored error codes,
No = lets to abandon them.
Allows, if necessary, to add a compensation value for the poss. temperature loss in
the system, so that the display shows the actual temperature of the pool water.
When you interconnect 2-10 MidiHeat devices, you decide which will be the Master
and the others are Slave 1, Slave 2... etc.
Time delay is factory set at 5 seconds. Can be changed to between 5-60 seconds.

A reservation for possible misprints. The right to change technical specifications and assortment is reserved.Color deviations may occur due to technical reasons.
MaintenanceNote that the electric heater is working only when water circulates in the system. It will not be heated if the circulation pump is switched off or if the desired pool temperature has been reached.If the electric heater does not heat the pool water for a long period it is recommended to turn off all main power switches. If the water in the system is still for more than a week, the electrical heater must be emptied of water.Attheriskoffreezing,thepowertotheelectricheaterandthepumpshouldbeturnedoffandboththeelectricheaterandthewhole system drained of water. Open the system drain valve and leave it open until it is time to start up the pool again.Whenbackwashingandcleaningthepoolsystemfilter,theelectricheatermustbeturnedoff.In areas with hard water, the electrical heater cartridges have a lime coating that reduces the electric heater power and the cartridgesservicelifeContactanauthorizedelectricianinordertoinspecttheimmersionheatersofthetankperiodicallyandremove this coating when necessary.
Emptying the electric heater1. Turn off the electric heater and turn off all main power before emptying.2. Closeshutoffvalve(pos.12,fig.2).3. Openshutoffvalve(pos.13,fig.2).4. Disconnect the electric heater outlet connection (marked with red arrow) a little to let air in.
The electric heater holds around 15 liters of water. Take care that all water comes out.5. Tighten the electric heater outlet connection when the electric heater is completely empty.6. Let drain valve stay open (water from the rest of the system may remain).
