■ At coding level 2, all codes are acces-

sible, including the codes at coding

level 1.

■ Codes that have no function due to the

heating system equipment level or the

setting of other codes are not dis-

played.

■ Heating systems with one heating cir-

cuit without mixer and one or two heat-

ing circuits with mixer:

The heating circuit without mixer is

designated "Heating circuit 1" and

If the heating circuits were given indi-

vidual designations, the selected des-

ignation and "HC1", "HC2" or "HC3"
