7.5.5 Electrical Heating
Elements - Model REH
Electric heating modules in Model REH are made up of two to six 5kw or three to twelve
10 kw heating elements depending on size and voltage of the unit. The elements are
bracketed together to make up the electric heat section assembly.
The electric heat section has either heating only analog controls (Option EG1 or EG2)
or digital heating/cooing controls (Option D12E or D12D). With Option EG1, operation
of the heating elements is controlled by a single stage thermostat. With Option EG2,
the heat section provides two-stages of heat in response to a two-stage thermostat.
Digital control is either two stage (Option D12E) or modulating (Option D12D).
See Paragraph 8.3.2 and the control instruction form (CP-PREEEVA-D12 B/C/D/E/
F/G) for digital control information.
