hi,
i have a 15 year old ideal classic gas 244 boiler, and have just had a new DT90E room thermostat fitted. the problem is the default settings for gas boilers is cycle rate 6 / min on off time 1 min, and the
Proportional band width 1.5.
with these settings the boiler cycled on and off constantly. the temp of 18 was reached and maintained well, but the constant cycling seemed unnecessary and annoying!
the heating engineers who were not that familiar with the thermostat recommended changing the settings to the oil boiler settings of : cycle rate 3 / on off 4 mins and leave the pb at 1.5
i have done this but wondered if this was in fact the best thing to do and also should i up the pb from 1.5 (it can go up to 3)?
as i said the stat does control the temp well - but the cycling bothers us as we feel we may use more gas ? rather confused by the settings as we did not have a room thermostat before!
also the boiler has a thermostat on it - dial, from 1-6 what is the best/most efficient setting for this.
many thanks for any help offered.
