FH 3 : 4.2 : 08.11 OJ Microline® ETN4-1999 T H E R M O STATS F O R U N D E R F LO O R H E AT I N G All-in-one Thermostat - For DIN Rail Mounting An “all-in-one” thermostat with extented temperature control range, suitable for a wide range of applications. Easy to operate and programme. • T he “all-in-one” thermostat is perfect for the application types: - Electrical floor heating - Frost protection - Ice & Snow melting - Cooling • Extended temperature range -19.5° to +70°C. • Input for night setback and frost protection. • Now also with cooling application – invertible relay function and differential temperature. • Optimum safety due to built-in 2 pole 16 Amp interrupter. • Easy menu navigation and programming. Programming is easy, ensuring the fastest and easiest set-up. • Big backlit display. • Delivered with new thin floor sensor, which makes mounting of sensor more comfortable than ever. PRODUCT PROGRAMME TYPE PRODUCT ETN4-1999 “All-in-one” thermostat for DIN Rail mounting incl. floor sensor ETF-944/99-H Remote room sensor ETF-144/99T Thin floor sensor MM-7595 Electronic Day/Week timer for DIN Rail ETNK Cover box for wall “All-in-one” now means much more The “all-in-one” Thermostat Comes with room sensing, room sensing and floor limitation, floor sensing mode only and regulator mode. If you need a thermostat for floor heating control, sauna, frost protection of pipes or cooling applications, the ETN41999 is an obvious choise. Large Differential Temperature Range The thermostat has a large differential temperature range of 6°C, for either lowering the cycle time of the relay or specifically to reduce the number of start cycles. Galvanic Isolation The new thin OJ sensor is of course supplied together with this thermostat. Furthermore, there is no restriction in using your current floor sensor even when from another supplier. © 2011 OJ Electronics A/S T. +45 73 12 13 14 STENAGER 13B F. +45 73 12 13 13 DK-6400 SØNDERBORG OJ@OJELECTRONICS.COM DENMARK WWW.OJELECTRONICS.COM BR-0991-A04b OJ ELECTRONICS A/S The thermostat can also decrease the heating period in %, when set to regulator mode. Frost Protection The input for frost protection can be set in thermostat mode as well as in regulator mode. Invertible Relay Feature The relay function can be inverted so that the thermostat can be used for cooling applications. Here the variable differential, up to 6°C, is also an advantage. Two External sensors It is possible to attach two external sensors to the thermostat for controlling a room thermostat with a floor limit sensor, protecting expensive wooden floor coverings from overheating. TECHNICAL DATA Supply voltage 230V AC ±10% 50/60Hz Standby power 0,5 Watt Output relay SPST 16A, resistive load or 1A inductive load Interrupter 2-pole, 16A Control temperature range (extended) -19.5 to +70°C Control accuracy ±0,4°C Floor limit range -19,5/+70°C Ambient temperature -19,5/+55°C during operation Night setback relative -19,5/+30°C Night setback regulator 1-100% Frost protection Abs. 0-10°C Frost protection regulator 1-100% Regulation principle PWM / PI or ON/OFF Housing IP20 Sensor type NTC (12 KΩ) 3m. max. 100m Display Segment – backlit Dimensions, (H/W/D) 88,5 / 52,9 / 57,3 mm Two individual inputs for setback temperatures The thermostat has built-in individual connectors for setting night setback and frost protection mode. MODE TEMPERATURE NIGHT SETBACK Lowering or increasing temperature by 10°C FROST PROTECTION Securing temperatures between 0 to +10°C Connector for easy „daisy chain“ of control wire. The thermostat can easily be mounted and wired side by side due to the spare live connector. Built-in 2 Pole Interrupter The built-in interrupter gives the best safety, and according to local regulations in some countries an external interrupter can be left out. © 2011 OJ Electronics A/S 3.4.2-08.11-ETN4-1999-GB · Subject to alterations · ® The OJ trademark is a registred trademark belonging to OJ Electronics A/S Night Setback The input for night setback can be set to increase and decrease the temperature.
