Dimplex RXPWIF Fully Integrated Pilot Wire Interface Dimplex RXPWIF Fully Integrated Pilot Wire Interface. The RXPWIF pilot wire interface unit provides additional system versatility by allowing ancillary appliances such as towel rails or water heaters to be controlled via a pilot wire programmer (typically RXPW4 4-zone controller). Also known as RX-PW-IF RX-PWIF RXPW-IF. FEATURES Pilot wire connection
- Pilot wire installations utilize an additional control wire linked between each heater. This is a 240V live conductor carrying a low current signal to activate the various modes on the heater electronic control. Up to 20 heaters per zone can be supported (dependent on controller & application). This system is ideal for new build applications as the pilot wire can be installed with the first fix wiring. As heaters require no additional receivers this offers a cost-effective means of central control. SPECIFICATIONS Allows control over ancillary appliances up to 3k W (16A) load (typically towel rail or hot water cylinder immersion heater) Installed local to the appliance being controlled. 38mm single gang wiring accessory back box required (not supplied) Switches power to appliance when programmer in comfort mode; disconnects supply when programmer in all other modes ideal to be used with RXPW4 4-zone pilot wire programmer
