The MENRED E51 is a weekly programmable floor heating thermostat with a clear LCD, manual control and scheduled operation. Up to six temperature events can be set per day to match occupancy and comfort requirements. Three output configurations are available for direct electric floor heating or on/off actuator control in hydronic underfloor heating systems.
The E51 thermostat measures the indoor temperature and switches the connected heating device or valve actuator according to the selected setpoint. When the measured temperature falls below the target, the thermostat calls for heat; when the target is reached, it switches the output off to help prevent unnecessary energy use.
Users can choose manual mode for a constant temperature or programmed mode for automatic weekly operation. The schedule provides up to six temperature events per day. A temporary override allows the user to change the current target temperature without rewriting the saved program; programmed operation resumes automatically at the next scheduled event.
All three E51 configurations support a built-in room-temperature sensor and an external floor sensor for floor-temperature limitation. The external limit can help protect temperature-sensitive floor finishes and reduce the risk of floor overheating when the thermostat is used with electric underfloor heating.
| Model | Rated Current | Output Type | Recommended Application |
|---|---|---|---|
| E51.716 | 16A | Switched powered output | Direct electric floor-heating load within the permitted rating |
| E51.713 | 3A | Switched powered output | On/off valve actuator or compatible low-current heating-control load |
| E51.723 | 3A | Potential-free contact | Hydronic floor heating, boiler or control interface requiring a dry contact |
The control-system designer or qualified installer must verify the operating voltage, load type, inrush current, actuator wiring and local electrical requirements. A contactor may be required when the connected electric-heating load exceeds the thermostat's permitted switching capacity.

The wide thermostat setting range does not mean every floor construction or finish may be operated at the same temperature. Follow the floor-covering supplier's permitted temperature and the project design limits.
E51.716 provides a 16A output for direct control of a compatible electric heating cable or heating mat load. MENRED's published guidance states a maximum electric-heating load of 3000W. For larger zones, divide the system into suitable control areas or use a correctly selected contactor under the direction of a qualified electrical designer.
E51.713 can control a compatible on/off valve actuator through its 3A switched output. E51.723 provides a 3A potential-free contact for projects that require a dry-contact signal. Confirm the actuator voltage, normally closed or normally open function and the required control logic before selection.
For compatible electric-heating products, see the MENRED electric underfloor heating mat. For water-based systems, compare the MENRED thermal actuators and valves range.
| Project Requirement | Recommended Configuration |
|---|---|
| Direct electric floor-heating control up to the permitted load | E51.716 — 16A |
| Powered 3A output for a compatible valve actuator | E51.713 — 3A |
| Dry-contact interface required by boiler or control equipment | E51.723 — 3A potential-free |
| Electric floor heating below timber, laminate or another temperature-sensitive finish | Use the external floor sensor and set the limit according to the flooring supplier's requirement |
MENRED supports distributors, floor-heating suppliers, HVAC contractors and project customers with model selection, thermostat-and-load matching, packaging discussion and project quotations. OEM requirements should be evaluated against order quantity, artwork, labeling, certification and target-market specifications.
Yes. E51.716 is the 16A version intended for direct control of a compatible electric heating load. MENRED's published guidance gives a maximum electric-heating load of 3000W. Verify the actual load, inrush current, wiring and local electrical code before installation.
Use E51.713 when a compatible 3A powered output is required, or E51.723 when the controlled equipment requires a 3A potential-free contact. Confirm the actuator or boiler input before selection.
The E51 weekly program supports up to six temperature events per day, allowing different settings for occupied, away and sleeping periods.
Yes. Temporary override changes the current target without deleting the program. The thermostat automatically returns to programmed operation when the next scheduled event begins.
Yes. The E51 series supports a built-in room sensor and an external floor sensor for floor-temperature limitation. Confirm whether the external sensor is included in the ordered package.
It helps reduce the risk of floor overheating and supports compliance with temperature limits specified by the flooring manufacturer, especially for electric heating under timber, laminate or other sensitive finishes.
Do not connect a larger load directly. Divide the heating area into suitable zones or use a correctly rated contactor designed by a qualified professional, while keeping the thermostat within its permitted switching conditions.
The E51.713, E51.723 and E51.716 configurations documented on this page are wired programmable thermostats. Wi-Fi and RS485 are not listed for these models. Select another MENRED thermostat series if remote or building-management communication is required.
