Winter Usage Setup Recommendations for 8-Zone Underfloor Heating Control Boxes

During winter, underfloor heating systems often run continuously for several months. If the control box is not set up properly during this period, two extreme situations can easily occur: either the room becomes unpredictable with fluctuating temperatures and poor comfort, or the system operates at high load for extended periods, significantly increasing electricity and gas bills. In reality, the effectiveness of underfloor heating depends not only on the equipment itself, but also on its usage and setup during winter. An 8-zone wired underfloor heating control box like the HR02 supports up to 16 room thermostats and 16 thermal actuator connectors, and also features boiler and pump delay settings, optional wireless network, and an Opentherm interface, providing a good foundation for stable operation in winter. However, this is contingent on these functions being used and set up correctly. Many users simply raise the temperature in winter, neglecting the importance of zone control, pump delay, and overall linkage settings. This not only fails to save money but also easily leads to frequent start-ups and shutdowns of the equipment.

Properly Plan the Temperature Control of the 8 Zones

The biggest advantage of an 8-zone control box is its zone control, which should be fully utilized during winter.

It is recommended to set separate zones for frequently used areas (such as the living room and master bedroom). Secondary spaces (storage rooms and guest rooms) can be set to lower temperatures individually.

This avoids heating the entire house at once, ensuring both comfort and energy efficiency.

The HR02 can control up to 16 room thermostats, allowing for individual room control even in an 8-zone system, providing greater flexibility during winter use.

Avoid excessively high temperature settings in winter

Many people turn the thermostats up very high as soon as they turn on the underfloor heating in winter, which is not advisable. It is recommended to maintain a relatively stable and comfortable temperature in the occupant area; lower the temperature appropriately at night or when no one is home. Underfloor heating is a low-temperature, continuous heating system; stability is more important than rapid heating. Setting temperatures in zones through the 8-zone control box reduces frequent boiler starts, making it more energy-efficient and less demanding on equipment.

Fully utilize the boiler and pump delay functions

The HR02 supports adjustable boiler and pump delay times, a crucial feature for winter use. Recommended setting: start the boiler first; delay for a period before starting the pump.

Benefits: Prevents pump dry running, reduces cold water circulation, and improves overall system efficiency.

In winter environments where multiple zones start and stop simultaneously, reasonable delay settings can significantly improve system stability.

Reasonable Arrangement of Thermal Actuator Connections and Zones

The HR02 supports up to 16 thermal actuator connectors. When using it in winter, pay attention to the following:

Multiple circuits in the same room should ideally be grouped into the same zone.

Avoid splitting a room into multiple zones, leading to repeated switching.

This allows for more concentrated thermal actuator action, reducing unnecessary frequent start-stop cycles and extending actuator life.

Winter Recommendation: Maintain Temperature Control

Underfloor heating is better suited for constant temperature operation in winter, rather than frequent switching.

The control box automatically controls the actuators based on thermostat feedback.

Reduce the frequency of action when the temperature approaches the set value.

This method, used in conjunction with an 8-zone control box, allows the underfloor heating to “heat slowly and continuously,” providing a more comfortable experience and greater energy savings.

Opentherm Linkage Setting Recommendations

If the HR02 is connected to the boiler via the Opentherm interface (optional), consider enabling the linkage mode in winter. The control box not only controls the switches but also influences the boiler’s operating status, allowing it to output heat according to actual needs. This setup effectively avoids high-frequency, full-power boiler operation, making it particularly suitable for families using underfloor heating extensively during winter.

Wireless Network Function for “Management”

The HR02 supports wireless network connectivity (optional). Recommended for winter use:

For checking status and remote adjustment

Frequent, large-scale remote temperature adjustments are not recommended

Overly frequent adjustments can disrupt the system’s operating rhythm and affect overall stability.

Winter is the season with the highest usage intensity for underfloor heating systems and is also the time when the control box settings are most tested. Based on the HR02’s 8-zone underfloor heating control box, by fully utilizing zone control, thermostat configuration, boiler and pump delays, reasonable allocation of thermal actuators, and optional Opentherm and wireless functions, stable operation and a comfortable experience can be achieved during the cold season. Winter underfloor heating aims for continuous, stable, and on-demand heating. Scientific settings can reduce energy consumption and equipment wear, ensuring the underfloor heating system operates healthily throughout the winter.
