Base unit

The base unit operates the actuators, which in turn affect the
flow of the supply water, to change the indoor temperature
using information transmitted from registered thermostats
and system parameters.
Up to six channels and eight actuators can be operated by the
base unit, which is typically located near the radiant manifolds.
The radiant illustration below shows the base unit with the
antenna and actuators.
