4.4 Smart Technology
Smart Control for water heaters will save en-
ergy and money for consumers by adapting
the energy used to the typical household re-
quirements for water heating. When the water
heater is first switched on, the smart control
operates like a normal thermostat for 7 days,
but during this time, will monitor and learn the
habits of the household. After 7 days the smart
control will reduce the energy used by the wa-
ter heater to match the requirements of the
household. The smart system stays in learning
mode and will alter the energy usage in a ac-
cordance with changes in household hot water
usage. 80322/3 includes embedded software
with a high performance algorithm which has
been tested and approved in both laboratories
and in field conditions.The algorithm has been
also tested as per the procedure defined in
prEN50440. 80322/3
Thermostat software implements a self setting
algorithm which is performed at first power
ON and repeated throughout the product life
whenever there is a need for product perfor-
mances optimization. This automatic setting
determines a set of parameters in direct rela-
tionship with the power of the heating element
and the tank capacity.
The Smart Themostat is designed to be directly
plugged into an immersion heating element
and includes:
•
Mechanical double pole disk safety

Safety limiter set between 65°C and 90°C
depending on ESWH
