MasterTemp’s easy-to-read controls make system operation and monitoring simple. Pool and spa temperatures can be pre-set and controlled with the push of a button. A digital display indicates the water temperature, and five LED lights give you system status and let you know if the heater needs service.

Easy to install or retrofit in even the tightest space — models from 200M to 400M BTUs — all measure 21L x 21W x 28H

Rotating digital display means more installation options and easier access to view operating information

Rustproof, tough composite exterior for long life

Available in natural gas and propane models.
