The “YY” numbers are the second and third digits and designate the option or combination of options. When
more than one option is selected, the “YY” option numbers are added, as in Examples B and C shown below.

-800 [X = 8, YY = 00]
(with 2.2 FLA high fan relay)
Example B
100-277V e4 with H + PIR options = Model e4-812 [X = 5, YY = (04 {H} + 08 {PIR}) = 12]
(with 3.6 FLA high fan relay)
Example C
OLD 24V e4 with IR5 + PIR options = Model e4-310 [X = 3, YY = (02 {IR5} + 08 {PIR} = 10]
NOTE: This assembly would be 01-9560.310 and calls for a 03-9460 which uses old P supply and 9496.
For the RF capable thermostats, the complexity engendered by the multiplicity of power supplies, logic boards,
and communications and other option call for a larger OPN incorporating a more granular scheme (Figure 13,
below). Table 9 lists the options available for the RF E528:
