Overview
COMFORT 10-16 pumps keep hot water at the tap without running all day. The T model controls by temperature, TDT adds a timer, and TA (AUTOADAPT) learns the household’s usage pattern and runs only when hot water is likely to be needed. The UP15-10 SU7P/TLC is the Comfort System kit: pump, timer, line cord and one under-sink comfort valve, for homes with no dedicated return line.
