EXTERNAL DUCT SENSOR
The optional external duct sensor (Order Item #1041536)
provides the ability to monitor the duct temperature at an
area beyond fresh air makeup and/or beyond other
devices and regulate the discharge air temperature
accordingly.
The duct sensor feature is enabled if the 4 bit is set in
Location 53 (L053). Once enabled, the ThermElect
system monitors temperature at both the duct sensor and
the output sensor during Y, W, or E calls from the ther-
mostat.
If there is a Y and a G call from the thermostat, the
ThermElect system operates the core blower at the
required speed to maintain the minimum output tempera-
ture as set in Location 48 (L048) at the duct sensor. If
there is only one call from Y, W, or E, then the system will operate the core blower at the required speed to
maintain the maximum output temperature as set in Location 49 (L049) at the duct sensor. The system is set to
turn off the core blower if the output temperature at the output sensor exceeds 150 degrees Fahrenheit.
LIFTING HANDLES
Optional lifting handles are available (Order Item #1302120) to aid in
moving the ThermElect Storage Module(s) into their final location. It is
extremely important to use caution when lifting a Storage Module.
Instruct workers to NOT walk under or place any body parts under
the Storage Module when lifting and/or moving.
