Steps Unit
"In case priority "Type" is set to "Water", system
gives priority to Yutampo operation. Air to Air
operation is not allowed during Yutampo heating-up
process by means HP operation.
In case priority "Type" is set to "Air", system gives
- - priority to Air to Air operation. Yutampo operation is
never performed in case there is at least one Air to
Air unit switched ON.
In case priority "Type" is set to "Mixed", system
allows mixed operation between Air to Air units and
Yutampo Unit. "
"This setting can be only edited in case "Type" is

Yutampo operation stops due to Maximum
Operation Time, electric heater shall start in order
to continue heating-up process until setting is
reached."
"This setting can be only edited in case "Type" is
set to "Mixed":
This option is allowed in case "Maximum Time" is
