The KTS 011 is a normally open (cool) thermostat that activates filter fans or heat exchangers when temperatures rise above the set point. The ZR011 combines both functions in a single unit, allowing you to independently control both heating and cooling devices from one thermostat.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do I install the ZR011 thermostat on a DIN rail?\u003c\/h4\u003e\n\u003cp\u003eA: The ZR011 features a clip-on design compatible with standard 35mm DIN rails (EN60715). Simply press the clip onto the rail until it snaps into place. No special tools are required. Wire connections are made at the bottom-mounted circuit interfaces using rigid wire up to 2.5mm with a clamping torque of up to 0.5 Nm.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What temperature range can the ZR011 control?\u003c\/h4\u003e\n\u003cp\u003eA: The ZR011 has an adjustable control range of 0°C to 60°C (32°F to 140°F). When setting the dial, be sure to account for the switching hysteresis of 7K (±4K) to determine your actual operating set point accurately.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is the ZR011 suitable for outdoor or humid environments?\u003c\/h4\u003e\n\u003cp\u003eA: The ZR011 carries an IP20 protection rating, which means it is designed for use inside enclosures or panels rather than direct outdoor exposure. It can operate in environments with up to 90% relative humidity (non-condensing) and withstand storage temperatures from -20°C to +80°C.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What is the difference between the KTO 011, KTS 011, and ZR011 thermostat models?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The KTO 011 is a normally closed (heat) thermostat that activates electric heaters when temperatures drop below the set point.
