DIMENSIONS

Same benefits as the TE93 with the addition of remote control:Proportional output provides fast and accurate positioning for zoneactuators and valves.Proportional integral control eliminates overshoot and droop.Adjustable dead band prevents overlapping between heating andcooling modes.Manual on/off override.Electronic temperature limiting and locking.Low and high limit temperature alarms can activate a dry contact toswitch an external control.Automatic heating/cooling changeover.Three speed automatic fan control with manual override.Direct or reverse acting outputs.System status indicators.Adjustable differential band.Infra-red remote control internal receiver (standard).Infra-red remote control transmitter (optional).Infra-red remote control external receiver (optional).
