Description
Description
ICMA 1100: room temperature control on the radiator
The ICMA 1100 thermostatic head, code 821100AC20, is a control with a liquid sensor for compatible thermostatic or thermostatic-ready valves, equipped with an M28×1.5 connection. It allows setting the room temperature in the 7–28°C range and acts on the radiator valve to help maintain it at the desired value. The white finish blends into domestic environments and the operation does not require electrical power.
- Model 1100, code 821100AC20.
- M28×1.5 connection.
- Liquid sensor, no electrical power required.
- Room control: 7–28°C.
- Frost protection position: 7°C; position 3: 20°C; position 5: 28°C.
- Limitation and locking of the setting using a fork.
- White color.
Main features
- Local radiator control: the control detects the room temperature and acts on the compatible valve; it does not replace the valve body.
- Liquid-sensing element: autonomous operation without electrical connections.
- Adjustment scale from frost protection to 5: allows choosing the desired value within the stated range.
- Limitation and locking: fork system to limit or fix the set temperature, following the manufacturer's instructions.
- Specific M28×1.5 connection: to be checked before purchase; it is not equivalent to M30×1.5.

* The values declared in the technical data sheet refer to the installation of the head on ICMA 774/775 valve bodies from 1/2”, 774+940/775+940 from 1/2” and 974/975 from 1/2”. These performances are not guaranteed with any valve having the same thread.
Applications
- Radiators with pre-installed valve: room temperature control on compatible thermostatic or thermostatic-ready valves.
- Head replacement: replacement on systems with correct M28×1.5 coupling, after checking the valve body.
- Room-by-room management: local setting of the radiator temperature, compatible with the operation of the system.
Check the thread, pitch and functional compatibility with the valve body before purchase. M28×1.5 and M30×1.5 are different connections. The head must be installed on a pre-installed valve: it does not make an incompatible manual valve thermostatic.
Follow the ICMA instructions for mounting, limitation and locking of the setting. Avoid conditions that prevent the sensor from correctly detecting the room temperature. During the summer period, ICMA recommends leaving the knob in the fully open position to reduce the risk of stem seizing. The frost protection position is a setting at 7°C, not a guarantee against freezing when the system cannot provide heat.

Frequently Asked Questions (FAQ)
Q: Can it be mounted on any radiator?
A: The type of radiator is not enough: a thermostatic or thermostatic-ready valve with an M28×1.5 connection is required. Also check the functional coupling with the valve body.
Q: What temperature does position 3 correspond to?
A: The declared reference is 20°C. The frost protection position corresponds to 7°C and position 5 to 28°C, within the intended control range.
Q: Does it require power or batteries?
A: No. The control with a liquid sensor operates without electrical power.
Q: Can I lock the setting?
A: The system provides temperature limitation and locking using a fork, to be used following the ICMA instructions.
