5.6.3 Testing of HeatPAC units
HeatPAC units supplied by Johnson Controls Denmark have, as far as possible, been function and per-
formance tested.
A performance test consists of simultaneous measurements of cooling or heating capacity, power con-
sumption and condenser capacity.
It is not a simple task to measure performance. High quality measuring and logger equipment is required
to make reliable and accurate measurements. Contact a Johnson Controls Denmark representative if a
performance test is needed.
