*1 The settings related to Zone2 can be switched only when 2 zone temperature control is enabled (when DIP SW2-6 and SW
2-7 (FTC) are ON).
*2 On: the function is active; Off: the function is inactive.
*3 When DIP SW1-1 (FTC) is set to OFF “WITHOUT Boiler” or SW2-6 (FTC) is set to OFF “WITHOUT Mixing tank”, neither Boil-
er nor Hybrid can be selected.
*4 Valid only when operating in Room temp. control mode.
*5 “*” of “*/kWh” represents currency unit (e.g. € or £ or the like)
*6 Valid only when operating in Heating room temperature.
*7 If asterisk (**) is chosen freeze stat function is deactivated. (i.e. primary water freeze risk)
*8 The settings related to Zone2 can be switched only when 2-zone temperature control or 2-Zone valve ON/OFF control is ac-
tive.
*9 When DIP SW5-2 (FTC) is set to OFF, the function is active.
*10 Do not change the setting since it is set according to the specification of flow sensor attached to the heat pump unit.
*11 The default setting is 1 pulse/kWh depend on the connected indoor unit.
*12 If booster heater equipped, the function is activated.
