The CommBox-600 is equipped with four (4) 50Amp 3-Phase relay contactors. This means that at 2-phase, you can connect up to 200 Amps worth of power, but at 3-phase, you can connect 150A per contactor. The relays are rated for 120-600 volts so the CommBox can be wired for 208, 277 and 480 using 3-Phase.
This page describes the ETO2 Controller and how it requires the installer to wire an external relay to connect the heaters/load to operate.
This Relay-25 fits in a standard single gang box. It is used in conjunction with the 4iE® Smart thermostat series as well as the Tempo thermostat, in order to expand the original 15 amp capacity. It is specifically designed for large applications beyond 800 sqft.
No, the ASE series does not have built in GFCI. Please click “Read More” for details.
The BOX system can be used with single-phase electric power. Click “Read More” for details.
There is no neutral leg on a double pole breaker and the polarity between the two sides does not match. This will cause the thermostat to trip and/or it will send too much voltage into a 120V heater.
When you have multiple floor heating systems being powered that require more than 15amps, you can use an additional 3iE as a relay as opposed to purchasing a separate generic relay which Warmup can supply.
The thermostats come with a 9’ sensor cable to detect the temperature under the floor finish. The end of the probe wire contains a capped sensor that should be evenly centered between two heating cables at least 12” into the heated area. At no time should the probe wire cross the heating cable.
While you can operate your floor heating system without the floor sensor probe it is better to have it installed. Click “Read More” for detailed information.
