Tower STTPRS Tamper‑Proof Thermostat — a pragmatic choice for simple, secure room control
July 29, 2026
0
A low‑complexity mechanical room thermostat that prioritises tamper resistance and reliability. The STTPRS is best where a single fixed setpoint and robust physical control are required — landlords, schools and communal spaces — but it’s a poor fit for anyone wanting programming, remote access or fine HVAC integration.
OP‑WFSTAT Wi‑Fi Digital Room Thermostat — a practical wireless stat for single‑zone homes
July 29, 2026
A compact, battery‑powered touchscreen stat paired with a small mains receiver, the OP‑WFSTAT blends simple on‑device scheduling with app control and optional OpenTherm support. It suits single‑zone homes that need remote access and boiler modulation without a full smart hub, but installers must note wiring and compatibility limits.
OP‑IHTGPT 24‑Hour Immersion Timer — a pragmatic, no‑frills daily scheduler
July 29, 2026
A basic, surface‑mounted mechanical timer aimed at straightforward daily control of immersion heaters and similar resistive loads. It’s simple to install and programme, offers 15‑minute scheduling steps and a removable link for volt‑free or mains switching. Best where low cost, simplicity and proven mechanics matter; avoid it if you need sub‑15‑minute control, outdoor protection or to switch modern lighting without a contactor.
OP-IHTDIGI Digital Immersion Timeswitch — a clear, low‑cost timer for simple water‑heating control
July 29, 2026
A compact, no‑frills digital timeswitch for immersion heaters and other resistive loads. The OP‑IHTDIGI offers 24‑hour and seven‑day programming with one‑minute resolution, volt‑free SPDT contacts and a handful of useful manual modes. It’s a practical choice where predictable, local timer control is required, but not for smart integration or high inductive loads.
Optimum OP-ECOSAVE Immersion Timer: A practical, no‑frills solution for Economy‑style hot‑water control
July 29, 2026
A technically clear assessment of the OP‑ECOSAVE immersion heater timer: who it suits, how it fits into typical cylinder setups, what it can and cannot do, and sensible installation and ownership considerations for households on multi‑tariff supplies.
OP-DRWF01 Wi‑Fi DIN‑Rail Timer — a compact concealed scheduler for single mains circuits
July 27, 2026
A small DIN‑rail mounted Wi‑Fi timeswitch that adds smartphone scheduling and voice control to a single mains circuit. Useful for concealed automation of heaters, pumps and lighting where loads stay within a 16 A resistive / 4 A inductive rating; not suitable as a motor starter or for weather‑exposed installations.
