Electrical wiring1.2 Electrical wiringThe power supply of the controller must only bemade by an external power supply switch (last stepof installation!) and the line voltage must be210 ... 250 Volt (50 ... 60 Hz). Flexible lines are tobe fixed at the housing by enclosed strain relief supportsand screws.The controller is equipped with 2 standard relays, towhich the consumers e.g. pumps, valves etc. can beconnected:• Relay 118 = conductor R117 = conductor R113 = ground clamp• Relay 216 = conductor R215 = neutral conductor N14 = ground clampThe temperature sensors (S1 up to S4) have to beconnected to the following terminals independentlyfrom the polarity:1/2 = Sensor 1 (e.g. Sensor collector 1)3/4 = Sensor 2 (e.g. Sensor store 1)5/6 = Sensor 3 (e.g. Sensor collector 2)7/8 = Sensor 4 (e.g. Sensor store 2)The power supply is effected to the clamps:19 = neutral conductor N20 = conductor L12 = ground clampPlease note:The relays are semi-conductor-relays for pump speedcontrol – they need a minimum load of 20 W (powerconsumption of the consumer) for faultless function.If auxiliary relays, motor valves, etc. are connected,the condenser which is enclosed in the mountingmaterial, must be connected parallely to the relevantrelay output.Attention: for connection of auxiliary relays orvalves, the minimum pump speed must be adjustedto 100%.Data communication / VBus ®The controller comes with a VBus ® (clamps 9/10) towhich external modules for data communication andenergy measuring can be connected. The externalmodules are connected to the VBus ® with optionalpolarity at clamps 9 and 10. It is possible to connectone or more modules as eg:• large display GA3/SD3• alarm module AM1• data logger DL2• VBus ® /LAN interface adapter for connection toPC/router, including RSC softwareExternal modules for VBus ® are available fromRESOL/SONNENKRAFT.FuseT4A 220 ... 240V~Temp.
