Number 23/24 – Temp sensor hot water recirculation
There are different ways to control hot water recirculation directly from Exotrol Multi . One way is to
measure the temperature on the domestic hot water pipe and thereby decide when the circulation
pump needs to operate. If using this method the sensor must be installed. Place the sensor on the
hot water recirculation return pipe at least 1m from tank 2 (or electric boiler). Insulate well.

Number 39/40/41 – External error relay
This block can be used if a signal to another control system is needed. The signal can be both NC or
NO. At normal operation without errors 39 and 40 is closed. If error occurs (or power failure) contact
between 40 and 41 will be true.
