Owner`s manual

Thermostat Connector
This connector is used to connect the Thermostat Keypad module to the Control Module. This
is a proprietary interface and can only be used with the specified modules. The Red and
White terminals supply power (3.3 VDC), the Green and Yellow terminals utilize a proprietary
communications protocol.
Furnace/AC Connector
This connector is wired to your furnace and/or air conditioner, or heat pump, and provides
control of your equipment. Refer to the Thermostat Connections section of this manual for
detail of terminal usage.
LAN Port
The LAN port is a standard Ethernet interface (IEEE 802.3 compatible with 10/100/1000
Base-T networks). This port operates at 10 Mbps (10Base-T). There are 2 LED activity
indicators built into the the connector. The green LED will be illuminated whenever there is a
physical link to your network (plugged in). The amber LED is illuminated when there is activity
on the port.
Power Supply
The power supply connector is used to power the BAYweb Thermostat if your furnace/AC
does not provide the common power wire (“C” or “X” terminal). See installation Step 1D.
Ideally the power supply should be plugged into the same circuit that powers the furnace/AC.
Status Indicators
Indicator Description
Heat 1 For conventional systems, this LED indicates when the thermostat is
signaling the furnace to produce stage one heat. For heat pump systems,
this LED indicates when the thermostat is activating auxiliary heat.
Heat 2 For conventional multistage systems, this LED indicates when the thermostat
is signaling the furnace to produce stage two heat. For conventional single
stage and heat pump systems, this LED indicates when thermostat is
signaling for the zone damper to open.
Compressor 1 For conventional systems, this LED indicates when the thermostat is
signaling the air conditioner to operate stage one cool. For heat pump
systems, this LED indicates when the thermostat is signaling the heat pump
to run the stage one compressor.
Compressor 2 For conventional systems, this LED indicates when the thermostat is
signaling the furnace to produce stage two cool. For heat pump systems, this
LED indicates when the thermostat is signaling the heat pump to run both
stages of the compressor.
