KOOLMASTER PP20-VS2 Tunnel 1-2 / inlet 1-2 / natural curtains 1-2 — Relays 7-8 and relays 15-20 have specially been designed for the connection of actuators. When actuators are connected to these relays, their open and close relays can never be activated at the same time. Feeding output — Feeder relays are used to stop feeders when a feeder run time alarm occurs. These normally closed relays open when the alarm condition is detected. *Accessible if the feeder alarm condition is enabled (sec. 12.3).
KOOLMASTER PP20-VS2 4.9. Clean Mode The clean mode is used to interrupt regular operations of the controller when the room is empty. When this mode is enabled, the controller closes all tunnel doors and curtains and then only provides a minimum level of heat and ventilation (optional). If minimum ventilation is used in the clean mode, all inlets will open to their respective minimum ventilation position; otherwise they remain closed.
KOOLMASTER PP20-VS2 5. TEMPERATURE SETTINGS The set point is a target temperature in the room. The activation of most outputs of the controller is based on this reference temperature. Outside set point — The controller can adjust the moving speed of natural ventilation curtains as a function of outside temperature. When this function is used, the controller refers to the outside temperature set point to control the moving speed. Set the outside temperature to the desired value.
KOOLMASTER PP20-VS2 5.2.3. Modifying Curve Points 6. VENTILATION & COOLING 6.1.2. Min Ventilation Settings You can adjust the temperature set point associated to all curve points while the curve is running. 6.1. 1. Select: 1. Select: Definition: Minimum ventilation cycles are activated when the average room temperature is below the start temperature of fan stage 1.
KOOLMASTER PP20-VS2 Relay status — Set the relay status to “On” if some On/Off relays need to be activated during the “On Time” portion of minimum ventilation cycles. Refer to section 4.8.2 to assign On/ Off fan relays. Minimum ventilation timer — Set the timer that is used by the on/off fan outputs in minimum ventilation. The timer is composed of an “On Time” and “Cycle Time” . Note that the “Cycle Time” includes the “On Time”, it must thus be longer than the “On Time”.
KOOLMASTER PP20-VS2 6.2.1.1. Operation of Fan Stages The controller has 12 fan stages which operate in a sequence to increase the level of ventilation as the room temperature increases. Each stage can activate two variable outputs, on/off outputs, and a combination of timer relays for cooling purposes. A fan stage is activated when the room temperature reaches its start temperature and is disabled when the room temperature decreases to its stop temperature.
KOOLMASTER PP20-VS2 6.2.1.3. Outside Temperature Compensation Stage 1 and 2 bandwidths can be adjusted automatically as a function of outdoor temperature compensation. As the outside temperature decreases, stages 1 and 2 bandwidths increase gradually to compensate for the change. The user specifies the bandwidth used in summer as well as the bandwidth used in winter for both variable outputs of stages 1 and 2. The bandwidths can be adjusted from 1 to 10°F (0.6 to 5.6°C).
KOOLMASTER PP20-VS2 Timer — If timer-based relays are assigned to some fan stages (sec. 4.8), set the “On Time” and the “Off Time” of each timer-based relay. On and Off Times can be adjusted from 0 to 99 minutes in increments of 15 seconds. 6.2.2.2. Changes Seasonal Temperature If the outside temperature compensation on the bandwidths of stages 1 and 2 is used, you must specify at what outdoor temperature winter and summer start. 1. Select: Current Conditions (Main Menu) Start/Stop* 6.2.3.
KOOLMASTER PP20-VS2 6.3. Natural Ventilation Curtains 6.3.1. Principle of Operation The controller can control two natural ventilation curtains. To operate these curtains, the controller refers to the average temperature reading of their assigned temperature probes (see sec. 4.7.3). The controller enters in natural ventilation when the average temperature of the probes that are assigned to a curtain reaches the Initial Opening Temperature of the curtain.
2. If the tunnel door is used in natural vent.: When the room temperature falls below the natural ventilation’s start temperature [A], the tunnel door and natural ventilation curtain open during the “Continuous Open” delay. When this delay has elapsed, both outputs operate according to the natural ventilation timer [B]. 6.3.3. Natural Ventilation Settings 1. Select: Current Conditions (Main Menu) 1st tunnel stage Temperature falls 1. If the tunnel door is not used in natural vent.
KOOLMASTER PP20-VS2 6.3.4. Curtain Compensation 6.3.5. Stopping Fans in Natural Vent. The controller can slightly adjust opening of the curtains as a function of outside temperature: as the outside temperature increases, the controller increases the opening time of the curtains. As a result, curtains open faster when the outside temperature gets warm. Likewise, when the outside temperature gets cold the controller increases the closing time of the curtains. This compensation is optional.
KOOLMASTER PP20-VS2 6.4. Tunnel Doors The controller can control 2 tunnel doors as a function of room temperature. Beginning of tunnel ventilation: The activation of tunnel ventilation is linked with the activation of a user-defined fan stage: when the start temperature of that chosen fan stage is reached, the tunnel door opens during the opening time or reaches the position (in %) that is associated with that stage. The activation of every consecutive fan stages causes the tunnel door to open further.
KOOLMASTER PP20-VS2 6.5. Air Inlets Inlet Opening 6.5.1. Principle of Operation The controller can control the opening of 2 air inlets: the opening of the first inlet can either be defined by a potentiometer or with a timer; the second air inlet can only operate with a timer. Set the operating mode of the first air inlet in the Installation Setup (sec. 4.5). When using inlets, the user has to associate an inlet opening with the start-up of each fan stage.
