5 Installing Thermostats
Include a communicating thermostat as part of the system when managing a typical forced air heating
and cooling system. You can also use a communicating thermostat to control a radiant heat zone
where traditional readout and manual setpoint adjustment is still desired at that location.
Installing a communicating thermostat
Communicating thermostats provide a way for the controlling computer to manage traditional forced
air thermostats through a browser interface. The number of zones will determine the quantity and
type of communicating thermostats.
Climate Automation Systems has approved the Residential Control Systems, Inc.
(http://www.resconsys.com
) TR16 communicating thermostat for use with the ENV system. Refer to
the RCS manuals found at http://www.resconsys.com/products/stats/serial.htm
for installation
instructions and for instructions on how to set a unique address for each thermostat.
Tie the communicating thermostats to the ENV system by connecting (daisy chaining) a pair of wires
to the RS485 terminals of each thermostat and continue to other RS485 devices. Ultimately the pair
of wires should terminate at the VLinx. A grounding wire should also be included and daisy chained
throughout.
