6-Stage Programmable Controller w/ Setpoint

The six stage electronic programmable controllers provide proportional control of outside and return (mixed air) dampers in sequence with staged heating and cooling equipment. Programming of the heating and cooling stages and relay assignment of heating and/or cooling plus operating level are accomplished by dual-in-line package (DIP) switches. Proportional heating and cooling outputs are available for valves or electric heat coils. The six stages can be programmed for heating, cooling, humidification, night setback and fan operation.

The heating, cooling and ventilation are precisely controlled from a single sensor operating with the programmable controller which employs a single temperature setpoint. (The CP-8261-333 setpoint is concealed while the CP-8261-702 setpoint is exposed). A nullband adjustment is also provided for separating the heating and ventilating/cooling functions between 2 and 14°F. Fan operations may be programmed to cycle in the unoccupied mode.

Features

• Sequenced Control: Staged and/or proportional heating, proportional control of outside and return (mixed air) damper, staged and/or proportional cooling. Heating and cooling cannot operate simultaneously.
• Single Setpoint (SPB): 55 to 85°F (13 to 29°C). Heating, cooling and ventilation are controlled from a single sensor and a single setpoint.
• Nullband Adjustment (SPA): 2 to 14°F (0 to 8°C); factory set at 3°F (2°C). Provides for separating the heating and ventilation/cooling.
• Mixed Air Low Limit Setpoint (SPC): 41 to 95°F (5 to 35°C).
• Relay Rating: 24/120 Vac, 1 amp. 240 Vac, 0.5 amp inductive. See Table 1.
• Adjustments: (For other adjustments See Table 2). Minimum Position, Minimum mixed air damper position (0 to 100%) factory set at 25%.
• Mixed Air Start Point: Factory set OP3 is 9 Vdc when IO2 is at 6 Vdc. The M.A.S.P. can be adjusted so that OP3 is 9 Vdc when IO2 is 3 Vdc.
• Unit Fan: May be programmed to cycle in the unoccupied mode.
• Relay Output: 6 relays can be programmed for heating, cooling or fan operation. Operational voltage level by dual-in-line switches.
• Mixed Air Sensor (optional): The controller can provide a separate mixed air control, or limit control in conjunction with proportional cooling output ramp.
• Cold Start: On power failure.
• Sensors: Any non-adjustable TS-8000.
• Control Output Voltage: See Table 2.
