Banico Pipe & Cylinder Strap-On Thermostat — TPS-1
The Banico TPS-1 is a commercial-grade surface-mounted contact thermostat designed for domestic and commercial heating pipes and domestic hot water storage cylinders. Operating via a precision liquid expansion sensing element with a stainless steel diaphragm, it delivers accurate surface temperature regulation from 0°C to 90°C. Housed in shock-proof, self-extinguishing thermoplastic rated to IP40, it is supplied complete with an adjustable spring-wire strap for fast, non-intrusive surface mounting.
Identification & Technical Guide:
Brand: Banico | MPN: TPS-1 | Internal Reference: FTBTPS1 | Temperature Range: 0°C to 90°C (Differential: ~6°C) | Electrical Rating: 16A (4A inductive) @ 250V AC, SPDT changeover contacts | Enclosure: IP40 self-extinguishing V0 thermoplastic | Compatibility: Universal surface attachment for 15mm to 54mm heating pipes and standard domestic copper/unvented hot water cylinders
Key Features
- Liquid Expansion Sensing: Incorporates a liquid-filled sensing capsule with a stainless steel diaphragm for rapid, drift-free thermal response to pipe and tank surfaces.
- SPDT Changeover Contacts: High-capacity 16A resistive / 4A inductive microswitch supports both heating demand (make on fall) and high-limit/cooling interlocks (break on rise).
- Robust Thermoplastic Enclosure: Base, cover, and calibrated dial are moulded from shock-proof, flame-retardant thermoplastic conforming to IP40 ingress standards.
- Universal Spring-Strap Included: Supplied with an elasticated tensioning wire fixing strap to clamp firmly onto pipes from 1/2" up to 2" or around cylinder bodies.
Installation & Compatibility Notes
Surface Contact Preparation: For accurate thermal transfer, clean the copper pipe or cylinder surface down to bright metal, removing all paint, scale, and insulation. On lagged cylinders, cut out a neat section of foam to allow direct metal-to-metal seating, and apply heat-sink thermal transfer compound between the sensor base and the cylinder wall.
Wiring & Positioning Advice: Mount on the boiler flow pipe (min. 1.5m away from the boiler heat exchanger) or at one-third to one-half the height of a hot water cylinder. Isolate mains electrical supplies before wiring into the SPDT terminals (Terminal 1 = Common, Terminal 2 = Satisfied/Cooling, Terminal 3 = Call for Heat).
