A wireless mobile device is used to control an HVAC temperature setpoint in a police vehicle containing a police dog. A wireless signal specifying a commanded temperature setting is checked to prevent malicious adjustments by a hacker. The commanded temperature setting is rejected when it is outside a predetermined range between an absolute minimum and an absolute maximum. When an outside ambient temperature is below a cold-day threshold, then the commanded temperature setting is rejected when it requests a temperature decrease. When the outside ambient temperature is above a hot-day threshold, then the commanded temperature setting is rejected when it requests a temperature increase. Otherwise, when the commanded temperature setting is not rejected as being outside the predetermined range, as being a decrease when below the cold-day threshold, or as being an increase when above the hot-day threshold, then the temperature setpoint is set to match the commanded setting.
