The CFox motor drive C-HC-0201F-E

The C-HC-0201F-E motor drive can be used for continuous control of radiator valves. The drive is powered from CIB and it is fitted with 2 analogue inputs and internal temperature sensor.

The drive is fitted with a quiet motor with a transmission; it has a typical stroke for most types of valves, which is approximately 1.5 mm (max. 2.5 mm). The exact value of the stroke can be set during the module configuration in the Mosaic environment. The drive enables manual or automatic adaptation to the valve. The C-HC-0201F-E module is mounted onto the valve to an arbitrary position using an adapter. However, is not recommended to mount the drive to the valve from the bottom, as the water leaking from the valve can cause damage to the drive.

An internal temperature sensor provides frost protection (when the temperature falls below 5 °C, then, regardless of the communication, the drive opens the valve). The drive also provides an automatic turning of the valve (after 30 days of standstill).

When making an order, you should always include an adapter for attaching the drive onto the controlled valve.There are adapters available for a variety of valves and valve inserts, see the Table below (an adapter consists of several parts, which are specified in Tab. 2).

Notes:

1. The motor drive is fitted with two inputs configurable as analogue (for temperature sensors), or as a binary potential free inputs (a window contact). So it is for instance possible to connect to the drive an ambient temperature sensor and a window contact simultaneously.

2. The cables for outdoor sensors should be connected to the terminal block under the drive housing, and the cable outlet is in the bottom part of the drive cover (see Fig. 2).

3. In addition to the drive it is necessary to order a relevant adapter for the specific valve (for an overview see the following Table).

4. For connecting outdoor temperature sensors or contact inputs, there are push-in terminals for wire cross section 0.14 ÷ 1.5 mm².

The electronic drive C-HC-0201F-E adapter must correspond with the type of thermostatic valve, on which the drive will be mounted. There are a large number or various types of thermostatic valves available on the market. On most of them the C-HC-0201F-E drives can be applied.

The basic variants of drives, including adapters for commonly used valves, are listed in the following table:

A more detailed list of the applicable valves, including the necessary elements for their connection, is listed in the following summary.

An overview of adapters or the connecting elements for valves and valve inserts

For an overview of valve types (including their images) and the appropriate adapters, see the following Table (click on the thumbnail to display a detailed image). As design changes in valve fittings are made continuously, the presented data may not be up-to-date.

Notes:

1. An assembly problem: The hex nut over the connecting thread of the valve does not have chamfered edges.. The plastic reducing ring must be hammered in by force. When the protrusions of the flange fit closely on the edges, they slightly open, which may impede screwing on the cap nut.The installation: The plastic reducing ring should be hammered in carefully to avoid contact between the flange protrusions and the edges of the valve metal nut. The cap nut should be screw in, so that the drive can still be turned. Only now the drive should be turned to the correct position and the cap nut can be completely tightened. The edges of the nut will cut into the plastic material of the reducing ring or the nut flange, but this will have no impact on its tight contact with the valve abutment surface.

2. What is meant here are the OVENTROP valves with an M30x1.5 mm thread for thermostatic drives.

3. In 2008 the Giacomini valves appeared on the market, with threaded mounting of the drive (M30x1.5). They are (at least for now) the R401H and R402H valves. The type of screw fitting is identical with the type for Heimeier.

4. A problem may occur when deploying the RK plastic ring on the cylindrical part of the valve head. If the ring cannot be pushed in place, you can somewhat increase the inner diameter of the ring by scraping a delicate chip, using a suitable tool.

5. The M28x1.5 thread is the following valves: 809, 808, 908, 933, 3809, 3808, 3908.

6. The M30x1.5 thread is in these valves: COMAP: D3805E, D3804E, D3908E, D3809EBC, SF3805, SF3804, SF3908.

An overview of adapter parts for valves (they can be ordered separately):

• EA006 is a cup nut with the thread M28x1.5 mm

• EA007 is a cup nut with the thread M30x1.5 mm

• EA008 is an adjustment ring for Danfoss RA valves

• EA009 is an adjustment ring for Giacomini-clip valves

• RK is a plastic (toothed) adapter ring; the ring tabs fit into the grooves of the drive flange

• RKx is a plastic (toothed) RK ring lowered in its cylindrical (full) part by about 2mm.

• DV is a spacer (cylindrical) with 10 mm in length

• DV is a spacer (cylindrical) with 7.5 mm in length

An overview of heating radiators fitted with valve inserts:

On the market there are hot water radiators from various manufacturers, which are fitted with valve inserts of various designs. In determining the specifications of the valve inserts, a partial guidance may be found in the following table.
