The EOS Power Extension Box 4 (PEB4) adds switching capacity to EmoTec D and Touch 3 controls so a single sauna can run several heaters at once. This l-xl size provides 4 relays.

It is only needed for multi-heater setups, supplying the relay capacity required to power each heater beyond the primary unit. Configurations can reach a maximum of 12 relay boards in total.

Power Extension Boxes are only compatible with the multi-heater Power Box; a single-heater Power Box must be upgraded to the multi-heater version first. Designed, engineered and built in Germany.
