ECB29EH electric heat sections provide field installed staged electric heat for Lennox Elite 10"
CB29M, Elite 12" CB30M, Elite 12" CB30U, and PowerMate" CB31MV blower coil units.
In heat pump applications, the electric heat is staged to
provide supplemental heat to meet desired comfort levels.
When the electric heat section is used in applications that
do not have a heat pump, the elements are staged to limit
heat so that it meets heating demands only.
Adjust element staging by changing the location of the
supply air temperature-selection
jumper on the ECH1
control board.

ent from the indoor thermostat, the control board temperature setting will automatically increase to the next
higher setting. Once the "Wl" demand is satisfied or
removed, the control board temperature setting will
automatically return to the jumper setting.
When using the ECB29EH heat section with the CB29M,
CB30M, CB30U or CB31MV series blower coil units, the
blower speed must be adjusted according to the size of
electric heat and blower coil unit. The minimum blower setting for each blower size, with any heat sections
in any application is HIGH. See specific blower coil
installation instructions for blower speed adjustment
procedure and location.
1 - Replace blower compartment
3 - Set thermostat
heat anticipator to 0.4 amps.
4 - Set thermostat
above room temperature.
5 - Verify that element staging and supply air temperatures are correct for the given application. If unexpected results are obtained, check heat pump and
heat section for normal operation. A table showing diagnostic codes for the EHC1 control board is
given in the troubleshooting
section of these
instructions.
The EHC1 control board can be adjusted to provide
four different
discharge air temperatures:
85°F
(29.5°C), 100°F (37.8°C), 115°F (46.1°C) and 130°F
(54.4°C). To adjust the factory setting of 85°F (29.5°C),
move the temperature selection jumper on the EHC1
control board to the desired setting (see figure 8).
The EHC1 control board uses the discharge air temperatu re value provided by the thermistor to maintain the
selected discharge air temperature by staging on the
required number of heating elements.
When higher discharge air temperatures are required
for comfort or to satisfy the heating load, change the
temperature selection jumper on the EHC1 control
board to a higher setting. In heat pump applications,
when the heat pump is on and a "Wl" demand is pres-
access cover.
2 - Restore power to unit.
6 - Set thermostat
to desired setting.
