Danfoss Ally 014G2461

Radiator thermostat

The Danfoss Ally radiator thermostat is a Zigbee 3.0 certified valve head with PID control. It sets 5 to 35 °C in 0.5 °C steps, measures every minute, runs about two years on two AA cells and accepts a room temperature from Edge.

Specifications

Danfoss states that the Ally is Zigbee 3.0 certified and speaks the same wireless language as other Zigbee devices. It is also sold under other names: Zigbee2MQTT lists the Danfoss 014G2463, the Hive UK7004240 radiator valve and the Popp 701721 on the same definition. The box includes adapters for Danfoss RA and M30 valves, Caleffi and Giacomini, and Danfoss lists further adapters for RAV, RAVL, RTD and M28 valves.1235

Where it is used

  • Room-by-room heating control in offices, schools and hotels with wet radiators, regulated on a room sensor where the radiator is boxed in.

    Indoor environmental monitoring

  • Finding rooms that heat outside occupied hours by trending each head’s heating demand beside the heating plant’s energy data.

    HVAC energy monitoring for commercial buildings

  • Large rooms with several radiators, where load balancing keeps the heads from fighting each other.

external_measured_room_sensor takes the room temperature in hundredths of a degree (2150 is 21.5 °C). With radiator_covered false, send it at least every 3 hours and ideally every 30 minutes or on a 0.1 °C change. With radiator_covered true, send it at least every 30 minutes and ideally every 5 minutes. After a timeout the head reverts to -8000, meaning no external value.5

For load balancing, enable load_balancing_enable on each head in a room and write the room’s mean to load_room_mean. Each head reports its own load_estimate.5

adaptation_run_status shows whether the head has found the valve’s closing point: none, in_progress, found, lost or lost_in_progress. adaptation_run_control starts or cancels a run.5

Setup

  1. Insert the batteries

    Insert the batteries and press the o button for 3 seconds until M appears on the display. M is mounting mode, ready for fitting to the valve.5

  2. Fit it to the valve

    Identify the valve by comparing its body with the outlines in Danfoss’s quick guide, fit the matching adapter and screw the head on.3

  3. Open pairing in Edge

    Open pairing on the Gateway’s Zigbee network in Edge, then press the o button briefly to put the thermostat into pairing mode.5

  4. Finish the installation

    When Edge shows the thermostat, press and hold the o button for 3 seconds to complete the installation.5

  5. Check one reading

    Confirm that Edge identifies it as Danfoss 014G2461, check that adaptation_run_status reaches found, then raise the setpoint and watch heating demand rise.

Common questions

Does the Danfoss Ally need the Danfoss Ally Gateway?
No. Danfoss states the Ally is Zigbee 3.0 certified, so it joins the Gateway’s Zigbee network directly and Edge reads and controls it without the Ally app or cloud.2
Is the Hive radiator valve the same device?
The Hive UK7004240 radiator valve uses the same Zigbee definition as the Ally, as do the Danfoss 014G2463 and the Popp 701721, so Edge exposes the same readings and controls for them.5
How often must Edge send the room temperature?
It depends on radiator_covered. When it is false, at least every 3 hours; when it is true, at least every 30 minutes. Sending every 5 to 30 minutes, or on each 0.1 °C change, keeps control tight.5
What do the E codes on the display mean?
E1 and E2 are temperature sensor faults. E6 is a jammed motor; the head retries after 20 minutes. E8 is a communication fault, and E9 means the valve cannot close properly, so check the installation.4
How do I factory reset it?
Remove the cover and take out one battery. Hold the black button next to the display while you refit the battery, release it after 10 seconds, then refit the cover.5
