CT系列将闭合延迟和断开延迟两种延时方式结合在一个单元之中,可用于控制加热和/或冷却设备中的风扇延时。 The CT includes bypass circuitry to allow it to operate with cooling anticipators ? 3000 ohms. 设计用于在24VAC的控制电路中运行。 Several CT modules may be combined to provide sequencing on of any number of loads and sequencing off of the same loads, such as electric heating elements.
运行(闭合延迟/断开延迟)
Forced Air Heating or Air Conditioning (as shown): When the thermostat closes, the compressor relay is immediately energized. 在固定闭合延迟(T1)结束时,风扇继电器通电。当恒温器接通时,压缩机继电器断电,断开延迟启动。当固定断开延迟(T2)结束时,风扇继电器断电。如果恒温器在断开延迟期间重新关闭,则断开延迟将重置,风扇继电器保持通电。如果恒温器在通电时关闭,闭合延迟(T1)照常启动。
Reset: Removing input voltage resets the output and time delays.
