Description
The C16 room thermostat by Fantini Cosmi is an electromechanical device with gas expansion designed for temperature regulation in both civil and industrial heating and air conditioning systems. It operates via a sensing element consisting of a stainless steel capsule containing saturated vapor, which detects thermal variations and actuates a snap-action micro switch with AgNi contacts. The temperature can be set on a scale from 10 to 30 °C with a differential of 0.8 K, and the thermostat body can operate within the range of -10 to 50 °C. The contacts support a rating of 10(2.5) A at 250 Vac, ensuring reliable system control. The device provides the option to lock or limit the adjustment range using pre-scored jumpers made of thermoplastic material, preventing tampering and allowing secure temperature management. It is rated IP20 and complies with EN 60730-2-9 standards, ensuring installation quality and safety. Electrical connection to the load is made via only two wires, facilitating system integration. The structure consists of a base, cover, and knob made of durable thermoplastic material, while the stainless steel sensing element guarantees durability and accuracy in detection. Additionally, an accessory, the TC16 frame, is available to enable mounting on standard round boxes of 60 mm or 75 mm with screw or clip fixing. This configuration supports simple and safe installation in various contexts, ensuring precise and reliable thermal control.
Advantages:
The C16 room thermostat offers significant advantages in terms of reliability and safety of use, thanks to its sensing element with an electrically welded stainless steel capsule containing saturated vapor, which ensures stable and precise response to temperature changes within an adjustment range from 10 to 30 °C with a differential of 0.8 K. The snap-action micro switch with AgNi contacts guarantees a rating of 10(2.5) A at 250 Vac, ensuring robustness and longevity of the electrical contacts. The thermostats construction, with base, cover, and knob made of thermoplastic material, contributes to good resistance and ease of installation. Furthermore, the ability to lock or limit the adjustment range via pre-scored thermoplastic jumpers offers protection against tampering, enhancing the devices safety and operational reliability. Compliance with EN 60730-2-9 standards guarantees its safety and suitability for civil and industrial heating and cooling applications. Installation is simplified by the connection to the load using only two wires and the availability of specific accessories, such as the TC16 frame, for mounting on different types of round boxes.
Installation:
Verify that the ambient installation temperature is within the allowed range for the thermostat body: from -10 °C to 50 °C
Prepare the electrical supply with a maximum voltage of 250 Vac and contact load capacity of 10(2.5) A
Electrically connect the thermostat following the snap-action micro switch wiring diagram with AgNi contacts shown in the manual
The connection to the load must be made with only two wires
Install the thermostat using the TC16 frame accessory, which allows mounting on:
60 mm round box with screw fixing
round box with clips (clips not supplied)
75 mm pitch round box
Take into account the mounting dimensions and fixings provided by the TC16 frame to ensure correct positioning
Lock or limit the temperature adjustment range using the pre-scored thermoplastic jumpers to prevent tampering or scale range modifications
Ensure adequate ventilation for the thermostat to keep the temperature within operational limits
Note: the thermostat has a differential of 0.8 K which must be subtracted from the value set on the adjustment scale from 10 to 30 °C
IP20 protection class, so protect from penetration of solid bodies larger than 12 mm and water
Installation compliant with EN 60730-2-9 standards
Screw fixings mandatory when using the 60 mm round box, while clip fixing is optional and requires separate provision
Follow the electrical connection sequence according to the diagram to ensure correct operation with opening between 1-2 and closing between 1-4 on temperature increase
Device unit weight 0.14 kg, to be considered during mounting for suitable supports

Use_Maintenance:
Usage and Configuration
The C16 room thermostat is used for temperature control in civil and industrial heating and air conditioning systems.
The temperature adjustment scale ranges from 10 °C to 30 °C with a differential of 0.8 K.
The thermostat operates with vapor pressure, opening contact 1-2 and closing contact 1-4 when temperature rises.
It is equipped with two pre-scored thermoplastic jumpers to lock or limit the adjustment range, preventing tampering or unauthorized changes.
The thermostat connects to the load via only two wires.
The device features a knob made of thermoplastic material for temperature adjustment.
Installation involves mounting on 60 mm round boxes with screw fixing, with clips, or on 75 mm pitch round boxes using the TC16 frame accessory.
Care and Cleaning
The manual does not specify particular cleaning or care procedures for the C16 thermostat.
Maintenance Frequency and Requirements
No specified frequencies or periodic maintenance interventions are indicated in the manual.
Tools or Materials Required
To lock or limit the adjustment range, a tool is needed to remove the pre-scored thermoplastic jumpers.
The TC16 accessory is available for mounting on various types of boxes.
Warranty Conditions and Usage Limits
The permissible temperature for the thermostat body is between -10 °C and 50 °C.
The contact rating is 10(2.5) A at 250 Vac.
The protection degree is IP20, so the device is not protected against penetrating dust or water sprays.
Warranty may be voided in case of tampering, unauthorized modifications, or use beyond specified temperature limits.
Installation and use must comply with EN 60730-2-9 regulations to ensure safety and compliance.
Problems_Solving:
1. Check the operation of the C16 room thermostat in case of incorrect temperature setting: verify that the thermoplastic jumpers are not pre-scored to avoid limitations or blocking of the scale range.
2. In case of tampering or limited scale range, remove or reposition the thermoplastic jumpers to restore full temperature adjustment.
3. For electrical switching problems, measure the contact rating and check continuity on terminals 1-2 and 1-4 during temperature variations; use a suitable multimeter and ensure AgNi contacts function correctly with loads up to 10(2.5)A 250 Vac.
4. Before intervening in the system, perform safety isolation by disconnecting the electrical supply and ensure protection against electric shocks (protection class I).
5. Verify that the stainless steel capsule containing saturated vapor shows no damage or leaks that could impair thermostat sensitivity.
6. Check that the temperature adjustment scale is between 10 ÷ 30 °C and that the permissible thermostat body temperature is within -10 ÷ 50 °C to guarantee correct operation and prevent malfunction due to thermal overload.
7. To identify and correct regulation faults, use the supplied wiring diagram (example of electrical connection) to check correct connections to terminals 1, 2, and 4.
8. During installation or maintenance, mount the C16 thermostat on TC16 frames compatible with 60 mm round boxes fixed by screws or clips (not supplied), ensuring correct fixing to avoid accidental disconnections.
9. Do not carry out unauthorized modifications or interventions that may invalidate certifications according to EN 60730-2-9 standards; in case of persistent malfunction, contact qualified technical support.
10. Periodically inspect the IP20 protection rating, ensuring absence of dust or excessive moisture that could impair proper thermostat functioning.
11. As prevention, check the condition of the thermoplastic base, cover, and knob to avoid mechanical breakage or overheating caused by wear.
12. In case of anomalies in switching signals or unstable temperature, perform a manual reset by temporarily disconnecting the thermostat from power and restoring standard mounting and adjustment conditions.
13. Use exclusively the integrated snap-action micro switch with AgNi contacts; replace only with identical components provided by the manufacturer to guarantee declared electrical characteristics (10(2.5)A 250 Vac).
14. Lock or limit the adjustment range exclusively using the pre-scored thermoplastic jumpers following instructions to avoid unauthorized tampering.
