depends on the type of controlled system, that is, on heat transmission
(piping network, radiators), building dynamics (building mass,
insulation) and heat output (boiler output, flow temperature)
(also refer to graph in Fig.
/ 1.1.6).
DIP switch 7 ON and 8 ON:
1 h/°C For slow controlled systems
DIP switch 7 ON and 8 OFF:
