Specifications

The H10 is a modular heating controller from Ubisys of Düsseldorf, built for DIN rail mounting in underfloor heating distribution cabinets. The base module holds 10 independent thermostats, each with a PI control loop, and 10 outputs that drive thermoelectric valve actuators directly by pulse-width modulation. It serves 10 heating or cooling zones in a two-pipe system, or 5 zones with both heating and cooling in a four-pipe system.²

Power

Mains. The H10/230-B runs from 230 V AC (85 to 264 V, 47 to 440 Hz). The H10/24-B runs from 24 V. Neither needs a battery; the clock has its own backup cell.²

Zones

10 heating or cooling (two-pipe), or 5 heating and cooling (four-pipe)²

Base modules

H10/230-B for 230 V AC, 50 Hz valves (order code 1205); H10/24-B for 24 V valves (order code 1199)²

Output rating

10 VA per output (230 V version); 5 W per output (24 V version)¹

Power dissipation

0.3 W²

Output switching

Solid state, PWM, staggered to spread valve inrush current²

Setpoint range

7 to 30 °C, in 0.5 °C steps⁴

Clock

Real-time clock with backup battery²

Extension modules

H10-XP pump control, H10-XS heating and cooling demand, H10-XW 1-Wire sensors, H10-XI wired thermostats²

Wireless

Zigbee 3.0 with Green Power, 2.4 GHz, 5 dBm transmit, -98 dBm receive sensitivity²

Zigbee tables

78 neighbours, 96 routes, 24 buffers for sleeping end devices²

Mounting

DIN rail, in heating distribution cabinets²

Housing

Flame retardant (V-0), black, RAL 9005²

Where it is used

• Underfloor heating demand per zone, lined up against the boiler’s firing and fuel use.

  Boiler performance monitoring

• Call for heat to a heat pump through an H10-XS relay, with each zone’s demand logged beside the heat pump’s output.

  Heat pump performance monitoring

• Room temperature per zone in apartments, offices and schools with wet underfloor heating.

  Indoor environmental monitoring

Interface

On the Zigbee network it joins as a router and extends the mesh for other devices.²

Endpoints 1 to 10 are the zone thermostats and endpoints 11 to 20 the matching outputs. In a four-pipe system zones 1 to 5 can switch between heating and cooling on their own.²

Each output applies the highest-priority valid steering value: emergency, then a level set over the network, then thermostat demand, then a wired thermostat, then the seasonal backup value. Switching an output on or off over the network overrides its thermostat.²

Each zone needs a temperature source, bound directly to its thermostat endpoint. Without one it stays in backup mode.²

After a power cycle the zones run in backup mode until fresh sensor reports arrive.²

Setup

1. Install it in the manifold cabinet

   Mount the base module on the DIN rail and wire the valve actuators to its outputs, with the right module for the actuator voltage. Ubisys requires a professional installer.²

2. Open pairing, then power it

   Open pairing on the Gateway’s Zigbee network in Edge and switch the H10 on. It blinks quickly while it searches, then five slow blinks when it has joined, or three quick blinks if it failed; it keeps searching after a failure.²

3. Reset a used unit first

   If it was on another network, hold the button behind the small hole on the front for about 10 seconds until the LED flashes (firmware 1.06 or later). Or power it for at least 4 seconds, give it three short power cycles of half a second to two seconds each, and leave it on.²

4. Give each zone a temperature

   Bind a Zigbee temperature sensor or thermostat to each zone’s thermostat endpoint, or fit H10-XW 1-Wire sensors. Zones without one stay at the backup valve opening.²

5. Check one zone

   Confirm that Edge identifies it as a Ubisys H10 with 10 zones. Raise zone 1’s setpoint above its temperature and check that its demand rises and its channel LED lights for longer.²

Common questions

Does the H10 measure room temperature?

No. Each zone needs a temperature source: a Zigbee or Green Power room sensor bound to it, another thermostat, or a 1-Wire sensor on the H10-XW extension. Without one the zone runs at a preset backup valve opening.²

Can it control electric underfloor heating?

Yes, through a solid-state relay on each circuit. The outputs are only rated for valve actuators, and heating foils often need 10 A or 16 A per circuit. Ubisys advises against electromechanical relays because of the PWM switching.²

Can it switch a boiler or heat pump?

With the H10-XS extension. It has two changeover relays, rated 1,800 VA at 230 V, that call for heat and call for cold, or act as dry contacts for a heat pump.²

What happens if the Zigbee network goes down?

Its real-time clock keeps its own schedules running. Sensors bound directly to a zone report to the H10 device to device, not through the Gateway. A zone that loses its temperature falls back to its backup value, and the front button can drive the valves by hand.²
