The Elta SEN-HY-I is a wall mounted humidistat with a built-in run-on timer. It switches ventilation on, or to boost, when room humidity passes an adjustable set point between 50 and 95% RH, then keeps it running for 1 to 25 minutes after humidity falls.It switches up to 2A at 230V 50/60Hz, has an LED status indicator, fits a single back box and has an IP40 rating for operating temperatures from 0°C to +35°C. Elta code ET-900005/A, with a 1 year parts only warranty. Humidity sensor 50 to 95% RH 1 to 25 minute run-on timer Single back box mounting What it is best used forAutomatic humidity control of extract fans and the humidity boost input of whole house units: bathrooms, shower rooms, en-suites, utility rooms and drying rooms, plus remote boost of Elta HAVA MVHR units from the wet room where the moisture is produced.It is a switching device rated at 2A, so it suits domestic fans and the switched inputs of MVHR units, not large commercial fans. It is IP40 and rated to +35°C, so do not mount it inside a shower enclosure or directly above a bath or cooker.Why choose this over alternativesMany domestic fans have a humidistat built in, but that sensor is in the fan, often high on a ceiling or wall away from the shower. A wall mounted SEN-HY-I senses the room itself and can boost a central unit such as the HAVA180H or HAVA280V MVHR, which has no sensor in each wet room.For timed run-on from a light switch with no humidity sensing, the 149S-A1729 run-on timer handles up to 5A and up to 4 hours.Installation notes Mount on a single back box in the room being ventilated, away from direct steam and heat sources. Wire to the fan or unit's switched (boost) input as shown in its instructions; do not exceed the 2A switching rating. Set the humidity threshold and the 1 to 25 minute over-run on commissioning, then check the LED as the set point is passed. Wiring by a qualified electrician with the supply isolated.
