“Pre-heating” function
it is possible to access the PRE-HEATING function selecting SET on the
main screen of the REC10.
Setting PRE-HEATING = 1 the boiler's domestic hot water function
activates. This function keeps the water in the domestic hot water
exchanger hot, to reduce standby times when a request is made. When the
pre-heating function is enabled, the symbol P comes on with a steady light
at the top with respect to the hot water icon. During burner ignition following
a pre-heating request, the symbol P starts flashing.
However, setting the parameter PRE-HEATING = 2 activates the Touch&Go
function, the boiler carries out, only if necessary, just one pre-heating cycle
after each take of domestic hot water.
To deactivate the pre-heating function, set the parameter to PRE-HEATING
= 0, the symbol "P" switches off.
The function is not active when the boiler is OFF.
