The three models will offer you the possibility to customize your central heating
system and hot water system as desired.
ALTHC023 is recommended for users that want to control only the Central Heating
or the Hot Water system.
ALTHC024 is designed to give you a full control with only one device of both your
Central Heating and Hot Water system.
ALTHC025 is the most versatile product of this line and lets you manage two
different Central Heating zones and the Hot Water with only one controller.
