The switching condition is indicated by the respective signal lamp For relay switching characteristics see Installation instruc tions for the transmitter under Item Function description For controlling loads the output can be configured in differ ent ways The functions subsequently listed can be combined in an INSTAT 868 04 3 1 Function Switching mode One transmitter controls one switching output Up to 4 transmitters control one output each channels 1 4 for heating ON OFF possibly channel 4 lights up see Sec tion 3 2 One or more actuators can be connected to each output For example see Fig 1 3 2 Function Pump logic Up to 3 transmitters control one output each channels 1 3 for heating ON OFF Channel 4 output serves as a common pump logic output The pump is switched off LED 4 extinguishes if none of the available transmitters has not called for heat for more than approx 10 minutes The pump is switched by the break contact of the relay This means that emergency operation of the heating system is possible in the event of a power fail ure if normally open actuators are used By parallel connection of the channel 4 outputs the pump logic can be extended to several receiving modules To avoid short circuits in the slave units remove bridges BR 4 BR 5 Supply slave units via terminal 7 8 of the master unit see Fig 2 This function is always activated as long as chan
