Application To control reheat coils and/or a fan stage in a fan-powered terminal unit.
The ADS-100 is controlled by a 2 to 10 VDC reheat output of a temperature controller. (TRS-M) Operation The ADS-100 is designed to switch up to three independent stages of reheat on and off, according to a 2 to 10 VDC signal. The three output stages are furnished with a triac output. Each stage can be adjusted
independently from each other over the 0 to 2.4° F throttling range of the TRS-M temperature controller. The ADS-100 is shipped pre-adjusted, as shown in the following table.
