When a DHW Demand is present, the Relay 9 / DHW con- tact terminals 30 and 31 is closed and the primary pump contact is closed. Priority can only be obtained using exter- nal wiring. During a priority override, the Relay 9 / DHW contact is opened until the heating system has recovered before returning to DHW operation, see Figure 19. This mode can be used if a DHW tank is piped in direct return and a DHW valve is installed
