A FLEXIBLE WAY TO CONTROL EXTERNAL HEAT
SOURCES FOR YOUR HOT TUB
Our new system interface lets you select, use and synchro-
nize alternative heat sources to efficiently keep the hot tub
water warm. Also acts as a hub to connect up to four single
button switches and one 4 button auxiliary switch.
Connected to the Y series, in.grid gives you the advantages of
using alternative heating sources. Connected to the CO port
of your hot tub control system, in.grid will act as a dispatcher
of external heating sources such as your heat pump or your
central house heating system.
With in.grid, you can choose one of its four modes of opera-
tion that suits you the best, depending on your external
heating system and your climate. Smart modes help you tak-
ing more advantage of your external heat source to optimize
your savings.
INSTALLATION
The in.grid provides a connection to a normally open dry-
contact relay on a spring-loaded female connector. The
connector accepts bare wire connections. The cable must be
passed through the already installed watertight grommet.
Use wire gage between AWG 24 and AWG 16.
Use cable with round jacket suitable for the watertight grom-
met. Diameter should be between 0.090'' and 0.250''.
The dry contact is rated for low voltage of maximum 24V and 4A.
