W8735D Telephone Access Module
APPLICATION
The W8735D Telephone Access Module (TAM) provides
remote telephone access to the HVAC system when used with
an EnviraCOM™ enabled thermostat such as the
TH9421C1004 VisionPRO IAQ Total Home Comfort System,
and the TH5320C1002 FocusPRO and T8635L1013
Chronotherm™ thermostat. These thermostats are used with
one or more of the following controls: a W8835A EnviraZone
panel, a THM5421C1008, W8635A and B Equipment
Interface Modules, or W8703 Damper Interface Modules. See
the product data sheets for these thermostats to see with
which devices each model would be used. The W8735D also
communicates with R7184P and U oil primary controls and
L7224U Aquastat ®, remote temperature sensors as well as
any other EnviraCOM enabled controls to communicate
current status and alert information.
The user can dial into the TAM and hear local temperatures
and system settings. The user defines the temperature and
a
humidity
limits and their alert priorities to best meet their
monitoring needs.
The W8735D provides remote telephone access for up to four
EnviraCOM independent channels. See Table 1 on page 2 for
the channels and zones available with each model. The
W8735D can be programmed to alert the homeowner and/or
an optional service contractor of abnormal conditions or
lockouts. Up to three different dial-out numbers (main,
backup, and contractor) can be entered in order to insure
alerts are well communicated.
a
Humidity is available only when used with the TH9421C1004
VisionPRO IAQ Total Home Comfort System.
INSTALLATION INSTRUCTIONS
Auxiliary input contacts allow integration of dry contact 24 Vac/
Vdc sensors to interface with the W8735D. In addition to
EnviraCOM thermostats, temperature alerts can be generated
using standard 24 VAC thermostats when interfacing with the
Auxiliary inputs. Auxiliary output contacts allow local
annunciation of alert conditions. Battery back-up enables the
W8735D to let the homeowner know the power is out at the
monitored location (optional 9V battery not included).
The W8735D can share a telephone line with most answering
machines and voice mail systems. The W8735D can be
prompted to pick up a call to gain access to the HVAC system
before the answering machine or voice mail are enabled.
Additionally, he W8735D is equipped with an emergency
telephone line disconnect feature activated when another
receiver in the premise is picked up while the W8735D is
connected. Full access to the W8735D is given when the
complete pass code is entered when prompted. Limited
access is given to contractors when the last five digits of the
programmed contractor telephone number is entered as the
pass code. Contractor access is limited to the W8735D Alert
History.
WARNING
Not a life safety or monitoring device.
The W8735D is not designed for use as a life safety
monitoring device to detect and generate alarms
based on the presence of toxic gases, smoke or fire
within residential homes or commercial buildings. The
incorporation of CO, CO
life safety sensors for monitoring by the W8735D is not
recommended, nor should the W8735D be used in lieu
of fire alarm, smoke detector, gas detector or other life
safety monitoring systems.
