this is a club run by and for its members. temperature sensing devices within the transmitter and receiver may relay temperatures to the external controller, which will then apply the correct power to the cooling device in order to keep the temperature of the transmitter and receiver unit, and application under charge at at safe values. do what is good, and you will have praise from the same. this could get tricky as my new hockey league has games on sundays or mondays. how does this difference influence what may be learned? if the above makes sense, then fine.
