INTRODUCTION The Timer has been designed for use in commercial and domestic installations as a wall mounted general purpose timer. Applications include: HVAC run time control Lighting on-time control Pump timing, including cyclic applications such as pool filtering. The timer can be triggered by a button press, or combined with another unit to allow operation only by authorized persons. The output from the timer can be used to control heavy equipment or lighting directly via an input on the equipment or with the addition of a high current relay or contactor. The standard solid state output is capable of switching low voltage AC or DC with loads up to about 100mA. The provides a very reliable output switching mechanism for use with small loads; more reliable than a relay. Electrical isolation on inputs and outputs ensure that there are no earth-loops or power supply problems when connecting the timer to various other equipment. The power supply current draw will typically not exceed 50mA due to the internal high efficiency switch-mode voltage regulator. Basic Feature List Standard single-gang flush box mounting (84mm mounting centers) Electrically isolated trigger input Zone input for optional movement detector Electrically isolated solid state output (100mA 24V AC) Power required = 12V to 24V AC or DC (typically 50mA maximum) Bright 4-digit red LED display Internal beeper Optional internal relay output (1A 230V AC rated) Optional second input for special functions Optional RS-485 network connection (future) Configuration Options TIM_4A0_A10 - standard configuration for HVAC control. 4-digit red LED display 3 button, standard white lexan input 1 and zone input solid state output 5-way and 8-way connectors firmware version A10 TIM_4A0_B10 - standard configuration for Lighting control. 4-digit red LED display 3 button, standard white lexan input 1 and zone input solid state output 5-way and 8-way connectors firmware version B10 Installation How the timer is to be used will determine the best installation position and wiring requirements. Custom Features There are a number of hardware features that have not yet been implemented in software. Due the possibilities we will activate and adjust these features to individual requests. We can also configure many standard operating characteristics to suit individual requirements. e.g. time increment value (step value for each button press).
