Slave 2
Master/slave-control
Several Midi Heat Digital devices can be connected in parallel (2-10 devices) and controlled from a (Master) electric heater
instead of adjusting individual temperature settings for every one of them.
The electric heaters connected to a shielded, paired 2-wire cable 0,25-2,5mm2. The part of the signal cable that is on the out-
side of two electric heaters should not be longer than 2 m.
When you have [Mode] on the display, press again the MODE button for addressing a device master (the one who decides) and
other devices as slaves (following the master). Note that you can not configure more than 1st master, only slaves or slaves with
the same address number (leading to communication error).

System configuration
Mode button (B) provides access to system settings and will be shown on display as [Mode]. DOWN arrow allows access and
making changes to the general system parameters.
Mode button provides access to the resp. parameter changes by means of arrow keys. Changes to the system parameters are
saved with the Mode button.
Return to the start menu is automatic after 5 seconds, or when selecting [Exit] in the d Mode button.
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.
