Dual-Zone External Thermostat

The Dual-Zone External Thermostat enables independent temperature management of two separate aquarium circuits from a single controller unit. Each zone features its own NTC temperature probe, setpoint display, and output socket, allowing the keeper to run two tanks at different temperatures from one wall outlet.

This controller is invaluable in fish rooms where bench space and outlets are at a premium, or in divided aquariums housing species with different temperature requirements. Both zones operate with digital accuracy to ±0.1°C, and each zone has its own independent alarm threshold.

The dual-output design also suits systems that combine a heater on zone 1 and a chiller or cooling fan on zone 2, enabling precise temperature regulation with both heating and cooling assets under one controller.
