Frequently Asked Questions - HR40 HONEYWELL

How do I install the Honeywell HR40 on my radiator?

The HR40 screws directly onto thermostatic radiator valve (TRV) bodies via an M30 x 1.5 connection. It is compatible without an adapter with Honeywell and Heimeier valve bodies. An adapter provided with the device makes it compatible with Danfoss RA and RAVL bodies. Adapters for Danfoss RAV, Herz, Oventrop, and Vaillant (VRHV/VRHF) are available as accessories.

What are the factory default programmed temperatures?

The HR40 is factory preset to 21°C (comfort) from 6:00 AM to 10:00 PM and 16°C (economy) from 10:00 PM to 6:00 AM. These values can be freely modified via the programming menu.

How many time slots can I program per week?

The HR40 offers 28 switching points per week, up to 4 per day. Each slot switches between comfort temperature and economy temperature. The smallest allowed switching interval is 10 minutes.

How does the HR40 window function work?

When a window is opened, the HR40 detects the sudden drop in temperature and closes the valve to prevent energy loss. The valve automatically reopens when the window is closed, at the latest after 30 minutes.

Can I temporarily change the temperature outside the program?

Yes, a manual adjustment is possible at any time using the control unit's dial. This temporary setting remains active until the next scheduled period change (comfort or economy).

What is the anti-blocking function of the HR40?

To prevent the valve from sticking after a long period of inactivity (especially in summer), the HR40 automatically fully opens and closes the thermostatic valve once a week. This function also protects against limescale.

Is the summer/winter time change automatic?

Yes, the HR40 automatically handles the daylight saving time change in spring and fall. The internal clock has a resolution of 1 minute.

How long do the batteries last in the HR40?

The HR40 operates with 2 LR6AA (Mignon) 1.5 V alkaline batteries, supplied with the device. Their lifespan is about 2 heating seasons. It is possible to use the HN40 accessory power supply to avoid using batteries.

Can the HR40 be used manually without programming?

Yes, manual control is possible directly via the valve lantern's adjustment ring. This mode allows you to force the valve to open or close independently of the electronic program.

Is there a version of the HR40 with a remote sensor?

Yes, the HR40 F version includes a remote detection and control unit connected by a 5 m cable. It is useful when the radiator is in an inaccessible place or not representative of the ambient temperature. The detection unit can also be added later via the HCW23-K accessory.

What should I do if the HR40 screen displays nothing?

Start by replacing the batteries with new LR6AA 1.5 V alkaline batteries. Also check that the control unit is properly fitted onto the valve lantern. If the problem persists after these checks, consult Honeywell support.

Is the HR40 CE certified?

Yes, the HR40 complies with the CE directive on radio shielding according to DIN50081-1 standard. It is designed for hot water heating systems with an operating pressure of 4 to 10 bar.

Installation

Only 4 Steps to Completion ...

It only takes a short time to install the HR 40:

• You remove the old thermostat.
• If necessary you install an adapter on the valve.
• You install the valve lantern.
• You attach the operating unit ... FINISHED!

1. Removing the old thermostat

1. Loosen the mounting of the old thermostat.
2. Pull the thermostat off the valve.

2. Mounting the valve adapter (optional)

1. Select the right adapter from the table.
2. If you need an adapter: Open up the adapter and push it onto the valve as far as the stop. Turn it while doing so until you feel it click into place.
3. For the Danfoss RAV adapter: Insert the adapter pin in the valve rocker.
4. If provided on the adapter: Tighten the adapter with the screw.

The Honeywell-Braukmann, MNG, Heimeier, Junkers, Landis & Gyr 'Duogyr' valves do not require an adapter. Adapters are available for Oventrop, Herz, Danfoss and Vaillant valves:

	Adapter manufacturer/type	Order No.
	Oventrop HU 01 (knurled nut M30x1)	073341076
	Herz HU 02 (knurled nut M28)	073341725
	Danfoss adapter set EVA 1-Danfoss	072031201
	RA (grey) (white) (enclosed)	RAVL (black)
	Vaillant adapter EHA 1VAI	072031082

3. Installing valve lantern

1. Turn the adjustment dial (3) of the valve lantern to the left until the nose (1) of the adjustment dial is positioned at the stop (2) of the housing.
2. Slide the valve lantern onto the valve or adapter. The flat area on the valve lantern head must point upwards.
3. Move the knurled nut forwards and tighten it firmly by hand (do not use a tool for this!).

The valve is now open and, with the central heating switched on, the radiator warms through.

4. Inserting or removing the operating unit

1. Turn the retaining bracket on the operating unit until it points upward.

1. Fit the operating unit onto the valve lantern, pushing it on as far as the stop. The flat surface of the valve lantern must be flush with the operating unit.

1. Turn the retaining bracket on the operating unit until the tip points rearward.

To remove the operating unit, reverse this sequence of operations.

Operating elements and display

(2) AUTO button for changing between Auto and Manu mode
(3) button for setting the comfort and economy temperatures
(4) PROG button for setting the time program
(5) Operating mode: Auto, Manu or Prog

Automatic functions

Window function

If you open a window so that the temperature at the HR 40 drops sharply for more than 3 minutes, the HR 40 closes the radiator valve in order to save energy. The display then shows the message Open.

When the temperature rises again – but no later than after 30 minutes – the HR 40 will resume normal operation.

Note: The window function can be ended at any time by pressing the PROG button or by turning the adjustment dial.

Valve protection

In order to protect the valve it is opened every Monday at midday.

CYCL is displayed.

Frost protection

If the temperature drops below 4^ , the HR 40 opens the radiator valve until the temperature rises above 6^ again. In this way, the HR 40 prevents the radiator from freezing. The symbol flashes as soon as frost protection is activated.

Note: Frost protection only works with the operating unit attached.

Summer/winter time

The HR 40 will switch to summer or winter time automatically.

Battery change display

When the bRt display flashes, the HR 40 remains functional. However, you should change the battery as soon as possible.

If bRt is displayed permanently, the HR 40 is inactive and the radiator valve is opened (frost protection).

Temperatures and control periods

The HR 40 changes between 2 setpoint temperatures...

• Comfort temperature:

(at the factory 21^ )

Economy temperature:

C (at the factory 16^

... and 2 periods:

• Heating period: Set at the factory to start 6.00 a.m., heating to comfort temperature
• Economy period: Set at the factory to start 10.00 p.m., lowering to economy temperature

Heating and economy periods are freely adjustable. The 2nd heating and economy period is optional.

Adjusting the setpoint temperature with the adjustment dial

The adjustment dial on the operating unit can be used to adjust the setpoint temperature at any time. The setting will apply until the next programmed heating or economy period. When the adjustment dial is turned the display shows the preset setpoint temperature.

The adjustment dial does not have a stop. By turning the ring clockwise, the following settings are shown:

Display	Setting
OFF	Radiator valve closed
5...30	Current setpoint temperature (poss. adjustment range)
On	Radiator valve fully open
