Description for Uponor (Wirsbo) A3030102

  • When it comes to radiant heating systems, not just any thermostat will do. That's why professional installers choose Wirsbo Radiant Thermostats. They are the first thermostats designed specifically for radiant floor heating.
  • Why a special thermostat for radiant floor heating? The dynamics of a radiant heating system differ from typical baseboard or warm air heating systems. Radiant systems always heat objects and mass, and need to be addressed differently than conventional thermostat logic.
  • The Wirsbo Thermostats offer two different control methods to handle this condition--differential and pulse-width modulation. Differential--When the measured room temperature falls 1F (0.5C) below the desired room setting, the control devices wired to the thermostat turns on.
  • Pulse-width Modulation--When the condition exists where the room temperature is 1 to 3F (0.5 to 1.5 C) below the room setting, the thermostat manages the on-and-off cycle using pulse width modulation. The on-and-off times vary depending on the difference between the room and set temperatures. The farther away the room temperature is from setpoint, the longer the on time. This prevents the room temperature from rising above the set temperature. The heating system runs continually at room temperature differences greater than 3 degrees F below setpoint.
  • These thermostats also feature digital filtering. This means that the thermostat measure the room temperature continuously. The thermostat's sensor detects even the smallest change, making it better able to react to a room's changing conditions. If all the room's temperatures were displayed as they are sensed, the temperatures shown would appear erratic and inconsistent. Filtering works by averaging the sensed values to ensure a smooth operation and display.
  • Wirsbo offers three thermostat models: Heat Only (A3030101), Heat and Cool (A3030102) and Heat Only, Three-wire (A3030103). The Heat Only (A3030101) and Heat and Cool (A3030102) thermostats are designed to operate in heating mode over two wires. These types of thermostats obtain their power for operation from taking voltage from the connected wiring. Different from other industry power-sharing thermostats, these eliminate any need for a third wire or battery, which makes the thermostats simple to install, wire and service.
  • And for those times when the two-wire thermostats aren't appropriate because of incompatibility with some third-party devices, Wirsbo also offers the Heat Only, Three-wire (A3030103).
  • No matter which thermostat you use, when you're selling radiant, you're selling comfort, The Wirsbo Radiant Thermostats feature special built-in software that provides the ultimate control that standard thermostats--when used with radiant heat--simply cannot. There's no overshoot, no undershoot--just constant, even comfort. Your customers will love the distinctive design and easy-on-the-eyes readout. But most of all,

Overall excellent but with some flaws

Comments about Wirsbo Radiant Thermostat (WT 2), Heat/Cool:

This wonderful thermostat solved my floor heating issue of "overshoot" of heating. This is the only product that can do that as I do not have a good option of an in-floor sensor.
However, the two button design is too complicated for my wife to use to change modes, especially when heat is needed in the morning and air conditioning in the afternoon. A simple heat-cool-automatic switch would be an improvement.
It does not have a "Fan only" mode in the heat and cool model and the sales brochure does not say that.
Also, the instructions are not well written and simple enough for the do-it-yourself person. The automatic change over delta from heat to cool is not clear. I could not find a wiring schematic that fit my circumstances.

Comments about Wirsbo Radiant Thermostat (WT 2), Heat/Cool:

As a home owner with many decades of experience in the fine arts of DIY, I found it impossible to install this (supposedly) simple thermostat.
Over the years, I've determined that most devices are designed to ensure the
employment of tradesmen, and the frustration of otherwise competent
home owners.

Works like it should. Install directions by manufacturer could be elaborated more for just a simple radiant heat install.

    Q:

    Does this thermostat allow for a slab sensor? If not, what is a good radiant thermostat one stage heat and cool that can use a slab sensor?

      A:

      This unit does not work with a slab sensor. We would recommend the Uponor A3040512 with the A3040079 slab sensor

    Q:

    The thermostat seems to have a minimum temperature setting at 59F. I was not able to lower the set point by hitting the minus key. I also tried to press and hold the minus key and that didn't work either. How can I lower the set point to bellow 59?

    Q:

    In considering a thermostat for a radiant floor heat system, are there options available that allow the use of a newer (cooler looking/functioning) thermostat that will still allow for multiple zones...say 4 or 5. Or will individual sensors and thermostats be required for each zone, thereby taking away a central command point and future internet controllabillity.

    • CUSTOMER CARE

      A:

      Multiple zones is not a possibility with this application. You need individual sensors and thermostats for each zone. As for an updated thermostat, we would recommend the Honeywell Prestige HD Thermostat (SKU: THX9321R5000).

    Q:

    Turned the thermostat off in spring by pressing both front buttons at same time, cannot get thermostat to start up in Fall. How do I reactivate thermostat?

    • CUSTOMER CARE

      A:

      According to the manual the unit has an off button to turn the unit on and off. The switch will have to be in the on position. Once in the on position you should be able to program the unit to the desired temperature settings.
