ProgrammingYour4DailyEvents
TheChameleonisan7‐dayprogrammablethermostat.Foreachdayoftheweekyou
areabletohave4timedsettemperaturechangesorprogrammedevents.Forclarity
theseeventsareconvenientlynamed“1”,“2”,“3”&“4”.

Thenumber“1”eventmaybeusedtosetthetemperatureofyourhomethatyou
wouldliketowaketo.

Thenumber“2”eventistypicallyusedtosetthetemperatureyouwishyourhometo
maintainwhilstyouareawayatworkperhaps.

Thenumber“3”eventisoftenusedtosetthetemperatureyouwishtobegreetedwith
uponreturninghomeattheendoftheday.

Thenumber“4”eventcanbeusedtosetacomfortableandenergyefficient
