Electric Heater Design
If the 10th digit in the model number is an “E”, the rooftop
unit was furnished with a factory installed electric furnace
(Example, DPS010AHCE). The Rebel rooftop units are
available with 4-stage heat output (see capacities in
Table 23
.
This packaged electric heat rooftop unit is designed for outdoor
non-residential installations only.
The electric heat design consists of a heating coil, DDC staging
control, and all operational safeties. The safety switches include
high-limit temperature switches and individual coil fusing.
The high limit switch is an automatic reset switch. It opens the
control circuit and shuts the heater down when the temperature
reaches the high limit switch closes again allows the heater
to run when the temperature gets below dead band. There is
a second level of protection with an auxiliary high limit switch.
This switch opens up and shuts the heater down when the
temperature exceeds the set point. This switch requires a
manual reset .
