Please read description fully before purchasing, thank you. This Siemens Ezetrol Plus Pool Spa Chemical Controller has been tested and is in good working order and was only removed due to a new plant room refit around 6 months ago, It is suitable for all water types and can be used in Swimming pools, hot tubs, koi ponds, fountains & water features and aquariums, this unit measures free Chlorine levels, PH levels and water temperature on the digital display. It has been fully stripped and cleaned, both chlorine and PH minus relays have been checked on manual mode as per pictures and both turn on and off as they should, 2 used probes are included which have been kept wet to reduce failure on install but due to the unit being out of action for a while I can't guarantee they will work properly again so new probes may be required once installed, I don't have any way of testing the probes or the flow switches as I don't own a pool so even though this unit was running fine on removal I can't guarantee the working condition as it may now require servicing/repair due to storage. No instructions but they are available easily to download online.
It is an easy machine to set up and use, display and buttons work perfectly too. Will be posted signed for due to size and value. The controller has been designed to offer easy control of the water chemistry to ensure it meets the desired levels. The controller is perfect for those who want to maintain their water treatment at the right levels for their swimming pool either commercial or domestic.
