Full speed is disabled if the outdoor temperature is below the set limit in P90.
  • Page 36 TAC 2413 Handbook Functional description The heat recovery is controlled to 100 % when FF starts, and the posi- tion of the heating valve is determined by the outdoor temperature. It is completely closed at outdoor temperatures ≥ 10 °C, and opens on a linear basis without breakpoints with decreasing outdoor temperatures.

  • Page 40: Night Cooling

    The cooling demand which exists during the summer period in or- der to keep the right temperature will result in high operating costs. For this reason, TAC 2413 makes use of the relatively cold night air to cool the building down as well. The consequences are that less cool air, if any, needs to be supplied on the following day, and in all, the energy consumption has been decreased.

  • Page 41: Co2 / Spc

    TAC 2413 Handbook Functional description 7.3.6 CO / SPC This function is chosen by using parameter P 55; 0 = no function, 1 = SPC, and 2 = CO By connecting an external 2–10 V DC control voltage to the SPC in- put, the current setpoint can be shifted, see the figure below.

  • Page 42: Mixed Air Damper

    7.3.8 Heat recovery TAC 2413 is able to control all types of heat recovery by using the output Y2. The control strategy is chosen using DIP switches 3 and 4. The control signal is 0–10 V, where 0 V = 0 % recovery and 10 V =100 % recovery.
  • Page 43 P 38. There may be freezing in heat exchangers, which will have effect on the efficiency of the recovery AHU. For this reason, TAC 2413 has a built-in defrosting function which is activated by short-circuiting the exhaust air sensor with the differential pressu- re sensor.

    10V=100% is equal to an open valve. The cooling coil will be engaged only when the temperature has in- creased so much that it has reached the cooling setpoint. TAC 2413 then switches from controlling by the heating setpoint to controlling by the cooling setpoint automatically.
  • Page 47 TAC 2413 Handbook Functional description The controller will return to heating control only when the supply air or room temperature has dropped to the “Heating setpoint”. The con- trol principle for both heating and cooling is to provide the highest possible comfort using the least possible energy by using advanced technology.

  • Page 48: Cooling Coil, Dx Cooling

    TAC 2413 Handbook Functional description 7.3.12 Cooling coil, DX cooling, D DX cooling may be chosen by using DIP switch 6, and the choice is only valid if room control applies. One step is controlled using K5, and if there are several steps, they are controlled via Y3. The control signal is 2–10 V and by using DIP switch 7, 0–10 V can be chosen.

  • Page 51: Timer Programs

    TAC 2413 Handbook Functional description 7.5 Timer programs TAC 2413 contains two weekly programs (1/1 and 1/2 speed) which control how the AHU starts and stops.
