The MENRED E91 is a touch screen floor heating thermostat for electric and hydronic underfloor heating systems. Its weekly program supports up to six temperature events per day, while manual mode and temporary override provide flexible control when the normal schedule changes. Three output configurations are available for direct electric-heating loads, powered control loads and potential-free control interfaces.
The E91 thermostat measures temperature and switches the connected heating device or control output according to the selected setpoint. When the measured temperature falls below the target, it calls for heat; after the target is reached, the output switches off. This on/off control helps maintain room comfort without unnecessary heating operation.
Users can select manual mode for a constant target temperature or programmed mode for automatic weekly operation. Up to six time-and-temperature events can be set per day. A temporary override changes the current target without deleting the saved schedule, and normal programmed operation resumes automatically at the next event.
The E91 series supports a built-in room sensor and an external floor sensor. The floor sensor can be used for floor-temperature limitation, which is especially important for electric heating and temperature-sensitive floor finishes. The permitted floor temperature must always follow the flooring supplier's instructions and the project design.
| Model | Rated Current | Output / Control | Recommended Application |
|---|---|---|---|
| E91.716 | 16A | Switched powered output | Direct control of a compatible electric floor-heating load |
| E91.713 | 3A | Switched powered output | Compatible on/off actuator or other low-current heating-control load |
| E91.723 | 3A | Potential-free contact | Hydronic heating, boiler or control interface requiring a dry contact |
Confirm the complete model, supply voltage, load type, actuator voltage, inrush current and terminal diagram before installation. A correctly rated contactor or additional control equipment may be required when the connected load exceeds the thermostat's permitted switching conditions.

The thermostat's wide setting range does not mean every floor construction or finish may operate at the same temperature. Follow the flooring supplier's maximum permitted temperature and the project design limits.
E91.716 provides a 16A output for direct control of a compatible electric heating cable or heating mat. MENRED's published guidance gives a maximum direct 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.
E91.713 can operate a compatible on/off control load through its 3A switched output. E91.723 provides a 3A potential-free contact for equipment that requires a dry-contact signal. Confirm the actuator voltage, normally closed or normally open function, boiler input and required control logic before selection.
For compatible electric-heating products, see the MENRED electric underfloor heating mat. For water-based systems, compare MENRED thermal actuators and valves.
| Sensor Use | Control Purpose |
|---|---|
| Built-in room sensor | Controls heating according to measured room-air temperature. |
| External floor sensor | Measures floor temperature for floor-based control where the selected configuration permits. |
| Room control with floor limit | Controls room temperature while stopping heat demand if the floor reaches the configured limit. |
| Project Requirement | Recommended Configuration |
|---|---|
| Direct electric floor-heating control within the permitted load | E91.716 — 16A |
| Powered 3A output for compatible control equipment | E91.713 — 3A |
| Dry-contact interface required by boiler or control equipment | E91.723 — 3A potential-free |
| Temperature-sensitive timber, laminate or similar floor finish | Use the 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. E91.716 is the 16A version for direct control of a compatible electric-heating load. MENRED's published guidance gives a maximum direct load of 3000W. Verify the actual load, inrush current, wiring and local electrical requirements.
Use E91.713 when compatible equipment requires a 3A powered output, or E91.723 when it requires a 3A potential-free contact. Confirm the actuator or boiler input before selection.
The E91 weekly program supports up to six temperature events per day for occupied, away and sleeping periods.
Yes. Temporary override changes the current target without deleting the program. The thermostat returns to scheduled operation when the next event begins.
Yes. The E91 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.
Er0 indicates an internal-sensor problem. Er1 indicates an external-sensor connection, selection or failure problem. Resolve the sensor issue before operating the heating system.
Do not connect a larger load directly. Divide the area into suitable zones or use a correctly rated contactor designed by a qualified professional.
Wi-Fi and RS485 are not listed for the E91.713, E91.723 and E91.716 configurations documented here. Select another confirmed MENRED model if remote control or building-management communication is required.
