TECO Replacement Digital Thermostat for TK 2 and TK 4 Aquarium Chillers

This is the original TECO digital thermostat for TK 2 and TK 4 aquarium chillers: the control unit with the LED display and SET and AUX buttons that switches the cooling cycle to hold your chosen water temperature. Replacing a faulty controller with the genuine part restores precise temperature regulation and keeps the chiller running as TECO designed it, with a direct fit and no modification needed.

Key features of the TECO Replacement Digital Thermostat

• Genuine TECO spare
• Digital LED display
• SET and AUX buttons
• Controls cooling cycles
• Direct replacement fit

Before you order

This controller is only for the TECO TK 2 and TK 4 chillers, so check the model plate on your unit before ordering. A blank display, a chiller that no longer starts or stops at the set point, or readings that drift can point to a faulty controller, but a damaged temperature probe or another part can cause similar symptoms, so ask a technician to confirm the fault first. Note your current settings before the swap so you can re-enter them afterwards.

Good to know

Switch off and unplug the chiller before fitting any spare part, check the part matches your model, and have the work done by a qualified technician if you are unsure.
