Should I Control My Radiant Floor With A Slab Sensor

The floor sensor will allow the floor to come up to a comfortable and constant temperature while the primary heating system takes care of the air temperature.

Should i control my radiant floor with a slab sensor. Remember that your slab will be about 75 degrees f. Mainly heated slabs radiate outward rather than downward so insulation on the edges of the slab is most important. This easy to install thermostat is a direct replacement for the tekmar thermostat 509. A slab sensor measures the floor temperature in the area where the radiant floor is located.

Use the grout joint for repairs. This sensor is designed to provide a thermostat with the ability to maintain a minimum slab temperature or help to limit the maximum slab temperature. One also needs to carefully read the installation instructions for the thermostat and properly set all the settings. Simple up and down buttons and a display with large type make this thermostat easy to read and use.

The result of using a slab sensor is that although the air temperature may overheat under certain conditions and may underheat under other conditions the floor temperature. If you have a floor heating system installed under a tile or stone floor and the floor sensor fails your grout joints can help. A floor control is also used when the primary purpose of the radiant heat is floor warming. It s possible to retrofit a replacement floor sensor into the grout joint.

This will allow the floor sensor to get an accurate reading without adding to the floor elevation. The slab sensor 079 is commonly used for floor temperature sensing in floor heating applications. This why the tekmar thermostat has these temp feedbacks. People do it of course but it s a very poor method of control.

The insulation phase is crucial for a radiant floor. The thermostat operates the radiant floor to maintain the floor temperature. It is impossible to control a slab with floor sensor only. Your slab must vary in temperature to change its output depending on how much heat you need.

A floor sensor is a fixed setpoint. Any cooler surface in contact with the slab will try to steal its heat. Bottom line for good hydronic radiant floor heating system temp control performance one needs to use slab outdoor air and indoor air temp feedback. A slab sensor 079 is included to measure floor temperature to protect the floor from overheating and enhance comfort.
