Wiring
If you are planning for a large project, Warmup recommends limiting the number of relays controlled by a single thermostats to 5.
A snubber is a device that is used to limit (or “snub”) voltage transients in electrical systems. In an electrical system where there is a sudden interruption of current flow, there can be a corresponding significant rise in voltage across the device.
If your thermostat has no display and will not turn on when power button is pushed, the thermostat could be wired incorrectly. Click here for more details.
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.
