ously. Both calls are being satisfied simultaneously because domestic hot
water priority has been disabled.

Central heating and domestic hot water calls are being received simultane-
ously. Domestic hot water call is being satisfied first because it has priority
over central heating calls.

will now switch back and forth between central heating and domestic hot
water calls until one call is satisfied.
